List of asteroids

From Academic Kids

This is a list of numbered asteroids, in sequential order. As of September 2004 there were over 90,000 numbered asteroids (and many more not yet numbered).

Many asteroids are fairly ordinary and not particularly noteworthy. For a smaller list of "interesting" asteroids, see List of noteworthy asteroids.

Numbering and naming conventions

After discovery, asteroids generally receive a systematic name (such as "1989 AC"), then a number (such as 4179), and finally (optionally) a name (such as "Toutatis"), in that order.

In modern times, an asteroid receives a sequential number only after its orbit is precisely known. Asteroids whose orbits are not (yet) precisely known are known by their systematic name (see provisional designation). This rule was not necessarily followed in earlier times, and some asteroids received a number but were subsequently "lost". All of these have now been recovered; the last "lost" numbered asteroid was 719 Albert (although 1915 Quetzlcoatl and (3360) 1981 VA have not been seen since 1985 (see [1] (http://cfa-www.harvard.edu/iau/lists/LastUnusual.html)), their orbits are known and close Earth approaches are due in 2062 and 2085 respectively).

For the reasons mentioned above, the sequence of numbers only approximately matches the timeline of discovery. In extreme cases, such as "lost" asteroids, there may be a considerable mismatch: for instance the high-numbered 69230 Hermes was originally discovered in 1937, but was lost until 2003. Only after it was recovered could its orbit be established and a number assigned. Before this, it was simply known as 1937 UB (its systematic name).

Only after a number is assigned is the asteroid is eligible to receive a name (for many years, Hermes was a rare exception, an unnumbered asteroid with a name). Usually the discoverer has up to 10 years to pick a name; some asteroids remain unnamed. Especially towards the end of the 20th century, with large-scale automated asteroid discovery programs such as LINEAR, the pace of discoveries has increased so much that it seems likely that the vast majority of "run of the mill" discoveries from now on will never receive names.

In rare cases, a very unusual object may receive an unofficial name before it is numbered. A recent example is 90377 Sedna, which officially had only the systematic name "2003 VB12" before it was numbered (90377) and, shortly thereafter, named in September, 2004.
