Two new NEAs and a Proposed Survey Telescope

Asteroid 2002 NT7 could hit in two decades; 2002 NY40 passes by August 17; and a large NEA search telescope is proposed.
(1) NEAR-EARTH ASTEROID (NEA) 2002 NT7
A small NEA called 2002 NT7 currently under observation has a remote possibility of hitting the Earth in 2019. The possibility will most likely be resolved within the next few days as new observations come in. It is reported here as an example of the sort of “detective work” associated with some of the newly discovered NEAs. (Assuming that you see nothing more posted here, you can assume that subsequent observations showed this object not to be a problem).
Asteroid 2002 NT7, a relatively large (H=16) Apollo asteroid with a still rather poorly determined orbit, has been on the Risk Pages of both NEODyS and JPL since July 18. The asteroid is easily observable; in fact it is observed practically every night, and its visibility will remain very good for the coming two months. As new observations come in, the situation will evolve in the next days and, as usual, either the probability associated with this object will go up somewhat, or, more probably, it will disappear.
The probability of impact is so small that this asteroid remains at a risk level on the Torino scale of 0 – meaning that the chances of impact from another unknown NEA of the same size or larger is greater than the chances of being hit by 2002 NT7. However, the impact probablity is not zero, and additional observations are needed to ensure that this object will not hit the Earth in 17 years.

Asteroid 2002 NT7: Low-Probability of Earth Impact in 2019
Asteroid 2002 NT7 currently heads the list on our IMPACT RISKS Page because of a low-probability Earth impact prediction for February 1, 2019. While this prediction is of scientific interest, the probability of impact is not large enough to warrant public concern.

Asteroid 2002 NT7: Potential Earth Impact In 2019 Ruled Out
Risk from Asteroid 2002 NT7 Eliminated
Risk from Asteroid 2002 NT7 EliminatedNew calculations based on fresh data reveal that asteroid 2002
NT7 will not strike Earth during the foreseeable future. Last week, preliminary
computations showed a miniscule chance the asteroid would collide with Earth in
the year 2019. The announcement grabbed
world headlines. However, the odds of impact were never higher than one in
260,000.It's common for estimates of asteroid danger to start out small, get even smaller,
then disappear entirely.
When astronomers first spot a near-Earth object (NEO),
they have little information to go on about its movements. As they project the
object's path
into the future, they allow
for a great deal of uncertainty. The object could pass anywhere within a
large region of the inner solar system, and that region sometimes includes Earth.
On following nights, astronomers can further observe the NEO's movements and
plot its course more precisely. The zone where they think the object might pass
begins to shrink, usually until it no longer includes Earth.Asteroid and comet impacts are a
critical factor in astrobiology. Paradoxically, they can apparently both
make a planet uninhabitable and hasten the evolution of life. Understanding
what
makes a planet habitable and how
life evolves are among astrobiology's
top goals.
2002 NT7: Media Splash but No Threat
Article Posted: August 12, 2002 NEA 2002 NT7 is quickly declared no danger, but leaves a debate concerning media coverage.
On July 18, initial orbital calculations for newly discovered asteroid 2002 NT7 indicated a remote possibility of impact in 2019 (see News Archive for June 22, 2002). On July 24 this remote chance of impact became an international media story based on initial published reports that the asteroid was “on a collision course with Earth”. As expected, however, additional observations quickly eliminated the possibility of an impact. The “all clear” for any impact in 2019 was released on July 26, and by August 1 continuing orbital improvements also eliminated a lower-probability impact in 2060. This progression of events reflects the normal working of the Spaceguard system. There is always an initial large uncertainty in the orbit of a newly discovered NEA, which is resolved as new observations are made.
So why all the media fuss about NT7? There is a wide divergence of opinion about what happened, much of it related to an apparent difference in press practices (and public expectations) in the USA and UK, the two countries in which most of the media stories originated. Simply put, the British Press seems to be more prone to exaggerated headlines and lead-ins, sometimes combined with a dose of humor – and the British public understands this and does not expect a high level of technical accuracy from their press. Americans generally hold science reporters to a higher standard, although alternatively, the Brits might say that Americans lack a sense of perspective and perhaps also a sense of humor.
One of the first to break the story on NT7 was David Whitehouse, senior science reporter on the BBC and holder of a doctorate in astronomy. His story began: “An asteroid discovered just weeks ago has become the most threatening object yet detected in space. A preliminary orbit suggests that 2002 NT7 is on an impact course with Earth and could strike the planet on 1 February, 2019 - although the uncertainties are large.”
In July 27 letter send to Benny Peiser, Whitehouse defends himself as follows: “Most reports said, quite rightly, that, based on the limited data available, it had an impact solution in 2019, but that more observations would almost certainly rule out any collision. I cannot agree that the vast majority of the reports give "no hint of the true situation," as one astronomer has commented… This is a subject of mixed messages as far as the media are concerned. I have seen many comments from astronomers and Nasa saying (after they had criticised the media) that NT7 will not hit us but then adding such phrases as ‘ALMOST no chance’ and ‘the impact probability is NOT ZERO’ and ‘there is a GOOD chance that this particular object won't hit us’ - actual quotes. Journalists can drive a cart and horses between ALMOST and NOT-ZERO. Ask the politicians about it.”
Whitehead feels that his lead statement that “2002 NT7 is on an impact course with Earth and could strike the planet on 1 February, 2019” was correct – but to my knowledge no astronomer who studies NEAs agrees. To say that the orbit is highly uncertain but allows the very low probability (of order 1 in 100,000) of an impact in 2019 is not equivalent to saying that the asteroid is “on an impact course with Earth” – at least the way I use the English language. Maybe this is an example of the difference between British and American usage.
The following article from Space.com explores these differences between US and UK press in much greater detail.

(89959) 2002 NT7
From Wikipedia, the free encyclopedia
(89959) 2002 NT7 (also written (89959) 2002 NT7) is a near-Earth object (NEO) that became the first object observed by NASA's NEO program to be assigned a positive rating on the Palermo Technical Impact Hazard Scale for a potential impact date of February 1, 2019. Despite inflammatory press reports, the object has a "low probability" of impact, approximately one in a million.
Further observations of the object have since re-rated the threat lower. As of July 25, 2002, the hazard rating on the Palermo scale had been lowered to -0.25. However, the discovery of an object with an initial hazard rating above 0.0 is still a significant event in the history of the NEO observation program.

Astronomical naming conventions
From Wikipedia, the free encyclopedia
In ancient times, only the Sun and Moon, a few hundred stars and the most easily visible planets had names. Over the last few hundred years, the number of identified astronomical objects has risen from hundreds to over a billion, and more are discovered every year. Astronomers need to be able to assign systematic designations to unambiguously identify all of these objects, and at the same time give names to the most interesting objects and, where relevant, features of those objects.
The International Astronomical Union (IAU) is the body officially recognized by astronomers and other scientists worldwide as the naming authority for astronomical bodies. In response to the need for unambiguous names for astronomical objects, it has created a number of systematic naming systems for bodies of various sorts.

[edit]Names of stars
Main article: Star designation
According to the IAU, apart from a limited number of bright stars with historic names, stars do not have proper names. Where historic names exist, these names are, with a few exceptions, taken from the Arabic language: this reflects the leading role of Arab culture in astronomy while Europe was experiencing the Middle Ages. See List of traditional star names for a list of some of these names.
There are no more than a few thousand stars that appear sufficiently bright in the Earth's sky to be visible to the naked eye, so this represents the limit of the possible number of stars available to be named by ancient cultures. This limit is approximate, as it varies by the acuity of any given observer's eyes, but ten thousand stars (the naked-eye stars to visual magnitude six) seems to be an upper bound to what is physiologically possible.
Estimates of the number of stars with recognised proper names range from 300 to 350 different stars. These tend to be the brightest stars, or stars that form part of constellation patterns with the brightest stars. The number of proper names for stars is greater than the number of stars with proper names, as many different cultures named stars independently. For example, the star known as Polaris has also at various times and places been known by the names Alruccabah, Angel Stern, Cynosura, the Lodestar, Mismar, Navigatoria, Phoenice, the Pole Star, the Star of Arcady, Tramontana and Yilduz.
With the advent of the increased light-gathering abilities of the telescope, many more stars became visible, far too many to all be given names. Instead, they have designations assigned to them by a variety of different star catalogues. Older catalogues either assigned an arbitrary number to each object, or used a simple systematic naming scheme such as combining constellation names with Greek letters. Multiple sky catalogues meant that some stars had more than one designation. For example, the star with the Arabic name of Rigil Kentaurus also has the Bayer designation of Alpha Centauri.
As the resolving power of telescopes increased, numerous objects that were thought to be a single object were found to be multiple star systems that were too closely spaced in the sky to be discriminated by the human eye. These and other confusions make it essential that great care is taken in using designations. For example, Rigil Kentaurus contains three stars in a triple star system, labelled Rigil Kentaurus A, B and C respectively.
Most modern catalogues are generated by computers, using high-resolution, high-sensitivity telescopes, and as a result describe very large numbers of objects. For example, the Guide Star Catalog II has entries on over 998 million distinct astronomical objects. Objects in these catalogs are typically located with very high resolution, and assign designations to these objects based on their position in the sky. An example of such a designation is SDSSp J153259.96-003944.1, where the initialism SDSSp indicates that the designation is from the "Sloan Digital Sky Survey preliminary objects", and the other characters indicate celestial coordinates.
The star nearest to Earth, our Sun, is typically referred to simply as "the Sun" or its equivalent in the language being used (for instance, if two astronomers were speaking French, they would call it le Soleil). However, it is sometimes called by its Latin name, Sol.
Finally, there are a few stars named after people.
[edit]Managing the initialisms of star catalogues
The IAU is the ultimate maintainer of the namespace of astronomical designations in catalogues of astronomical objects. The purpose of this is to ensure that names assigned by these catalogues are unambiguous. There have been many historical star catalogues, and new star catalogues are set up on a regular basis as new sky surveys are performed. All designations of objects in recent star catalogues start with an "initialism", which is kept globally unique by the IAU. Different star catalogues then have different naming conventions for what goes after the initialism, but modern catalogues tend to follow a set of generic rules for the data formats used.
[edit]Star-naming Companies
Several for-profit star-naming companies sell the right to list stars in their private registries under whatever name the buyer so chooses. However, the IAU (and, therefore, most astronomers) do not recognize those names as "official" (although the companies themselves do). Most astronomical organizations (and most international scientific organizations) say that the IAU is the only body allowed to officially name heavenly objects. (It is important to realize that the companies, in fact, often 'doublebook' prominent stars with each other; and sometimes the same company will assign different names to the same object. The customer, of course, is not informed of any prior claim.)
[edit]Names and boundaries of constellations
The sky was arbitrarily divided into constellations by historic astronomers, according to perceived patterns in the sky. At first, only the shapes of the patterns were defined, and the names and numbers of constellations varied from one star map to another. Despite being scientifically meaningless, they do provide useful reference points in the sky for human beings, including astronomers. In 1930, the boundaries of these constellations were fixed by Eugène Joseph Delporte and adopted by the IAU, so that now every point on the celestial sphere belongs to a particular constellation.
[edit]Names of supernovae
Supernova discoveries are reported to the International Astronomical Union's Central Bureau for Astronomical Telegrams which sends out a circular with the name it assigns to it. The name is formed by the year of discovery, immediately followed by a one- or two-letter designation. The first 26 supernovae of the year get an upper case letter from A to Z. Afterward, pairs of lower-case letters are used, starting with aa, ab, and so on. Four historical supernovae are known simply by the year they occurred (SN 1006, 1054, 1572 (Tycho's Nova), and 1604 (Kepler's Star)); starting with 1885, the letters are used, even if there was only one supernova detected that year (e.g. SN 1885A, 1907A, etc.) —this last happened with SN 1947A. The standard abbreviation "SN" is an optional prefix. As instruments improve and the number of astronomers (both professional and amateur) searching increases, more and more supernovae are observed each year - currently at least 500 a year. For example, the last supernova of 2006 was SN 2006ue, indicating that it was the 551st supernova found in 2006 (a record year, in fact).
[edit]Names of galaxies
Like stars, most galaxies do not have names. There are a few exceptions such as the Andromeda Galaxy, the Whirlpool Galaxy, and others, but most simply have a catalog number.
In the 19th century, the exact nature of galaxies was not yet understood, and the early catalogs such as the Messier catalog simply grouped together open clusters, globular clusters, nebulas, and galaxies, 110 in total. The Andromeda Galaxy is Messier object 31, or M31; the Whirlpool Galaxy is M51. The New General Catalogue (NGC) (J. L. E. Dreyer 1888) was much larger and contained nearly 8,000 objects.
[edit]Names of planets
The brightest planets in the sky have been named from ancient times. The scientific names are taken from the names given by the Romans; Mercury, Venus, Mars, Jupiter and Saturn. Our own planet is usually named the Earth, or the equivalent in the language being spoken (for instance, two astronomers speaking French would call it la Terre). However, it is only recently in human history that it has been thought of as a planet. The Earth, when viewed as a planet, is sometimes also called by its Latin name Terra (some older science fiction uses the alternate Tellus).
At least two more bodies were discovered later, and called planets:
Uranus, discovered by William Herschel in 1781
Neptune, discovered by Johann Gottfried Galle in 1846 (based on predictions by Urbain Le Verrier and John Couch Adams)
All of these planets were given names from Greek or Roman myth, to match the ancient planet names. However, this was only after some controversy. For example, Sir William Herschel discovered Uranus in 1781, and originally called it Georgium Sidus (George's Star) in honour of King George III of the United Kingdom. French astronomers began calling it Herschel before German Johann Bode proposed the name Uranus, after the Greek and Roman god. The name "Uranus" did not come into common usage until around 1850.
Starting in 1801, asteroids were discovered between Mars and Jupiter. The first few (Ceres, Pallas, Juno, Vesta) were initially considered minor planets and joined the ranks of the planets. As more and more were discovered, they were soon stripped of their planetary status. On the other hand, Pluto was considered to be a planet at the time of its discovery in 1930, as it was found far beyond any then-known asteroid's greatest distance from the Sun.
Following this pattern, several hypothetical bodies were given names:
Vulcan, for a planet within the orbit of Mercury;
Phaeton, for a planet between Mars and Jupiter which was the precursor of the asteroids;
Themis, for a moon of Saturn;
Persephone (and several other names), for a trans-Plutonian planet
Some sixty years after the discovery of Pluto, a large number of large trans-Neptunian objects began to be discovered. Under the criteria of classifying these Kuiper belt objects (KBOs), it became dubious whether Pluto would have been called a planet were it discovered in the 1990s. Its mass is now known to be much smaller than what was once thought and, with the discovery of Eris, it is simply the second largest known trans-Neptunian object. In 2006, Pluto was reclassified to a different class of astronomical bodies known as dwarf planets.
[edit]Natural satellites of planets
The Earth's moon is simply known as the Moon, or the equivalent in the language being spoken (for instance, two astronomers speaking French would call it la Lune). It is sometimes called Luna (which is simply Latin for "moon"). Natural satellites of other planets are generally named after mythological figures. Satellites of Uranus are named after characters from works by William Shakespeare or Alexander Pope.
When satellites are first discovered, they are given provisional designations such as "S/2000 J 11" (the 11th new satellite of Jupiter discovered in 2000) or "S/2003 S 1" (the 1st new satellite of Saturn discovered in 2003). The initial "S/" stands for "satellite", and distinguishes from such prefixes as "D/", "C/", and "P/", used for comets. The designation "R/" is used for planetary rings. These designations are sometimes written like "S/2003 S1", dropping the second space. The letter following the category and year identifies the planet (Jupiter, Saturn, Uranus, Neptune, Pluto; although no occurrence of the other planets is expected, Mars and Mercury are disambiguated through the use of Hermes for the latter). When the object is found around a minor planet, the identifier used is the latter's number in parentheses. Thus, Dactyl, the moon of 243 Ida, was at first designated "S/1993 (243) 1". Once confirmed and named, it became (243) Ida I Dactyl.
H = Mercury (Hermes)
V = Venus
E = Earth
M = Mars
J = Jupiter
S = Saturn
U = Uranus
N = Neptune
P = Pluto
Note: The assignation of "H" for Mercury is specified by the USGS Gazetteer of Planetary Nomenclature; since they usually follow IAU guidelines closely, this is very likely the IAU convention, but confirmation is needed.
After a few months or years, when a newly discovered satellite's existence has been confirmed and its orbit computed, a permanent name is chosen, which replaces the "S/" provisional designation. However, in the past, some satellites remained unnamed for surprisingly long periods after their discovery. See Naming of natural satellites for a history of how some of the major satellites got their current names.
The Roman numbering system arose with the very first discovery of natural satellites other than Earth's Moon: Galileo referred to the Galilean moons as I through IV (counting from Jupiter outward), in part to spite his rival Simon Marius, who had proposed the names now adopted. Similar numbering schemes naturally arose with the discovery of moons around Saturn and Mars. Although the numbers initially designated the moons in orbital sequence, new discoveries soon failed to conform with this scheme (e.g. "Jupiter V" is Amalthea, which orbits closer to Jupiter than does Io). The unstated convention then became, at the close of the 19th century, that the numbers more or less reflected the order of discovery, except for prior historical exceptions (see the Timeline of discovery of Solar System planets and their natural satellites).
[edit]Geological and geographical features on planets and satellites
Main article: planetary nomenclature
In addition to naming planets and satellites themselves, the individual geological and geographical features (craters, mountains, volcanos and so forth) on those planets and satellites also need to be named.
In the early days, only a very limited number of features could be seen on other solar system bodies other than the Moon. Craters on the Moon could be observed with even some of the earliest telescopes, and 19th century telescopes could make out some features on Mars. Jupiter had its famous Great Red Spot, also visible though early telescopes.
In 1919 the IAU was formed, and it appointed a committee to regularize the chaotic lunar and Martian nomenclatures then current. Much of the work was done by Mary Adela Blagg, and the report Named Lunar Formations by Blagg and Muller (1935), was the first systematic listing of lunar nomenclature. Later, "The System of Lunar Craters, quadrants I, II, III, IV" was published, under the direction of Gerard P. Kuiper. These works were adopted by the IAU and became the recognized sources for lunar nomenclature.
The Martian nomenclature was clarified in 1958, when a committee of the IAU recommended for adoption the names of 128 albedo features (bright, dark, or colored) observed through ground-based telescopes (IAU, 1960). These names were based on a system of nomenclature developed in the late 19th century by the Italian astronomer Giovanni V. Schiaparelli (1879) and expanded in the early 20th century by Eugene M. Antoniadi (1929), a Greek-born astronomer working at Meudon, France.
However, the age of space probes brought high-resolution images of various solar system bodies, and it became necessary to propose naming standards for the features seen on them.
