- This has been covered before in this newsgroup. This object is
- definitely NOT a _planet_, but rather a minor planet or possibly even
- a comet. There are two other objects, namely (2060) Chiron and
- (5145) Pholus which are of comparable size in the outer solar system.
- The interesting thing about 1992 QB1 is that it may be the first member
- of a class of objects in the "Kuiper Belt", thought by some to be the
- source of low inclination, short period comets, and previously
- undetected. The Kuiper belt is hypothesized to lie outside of the
- orbit of Neptune consists of relatively low inclination objects.
-
- The latest orbital elements for 1992 QB1 are:
- a=44.31 AU, e=0.10, i=2.2 degrees
- If these elements hold, (and I should remind you that even though
- the arc is about 171 days on the observations, it has been observed
- over an exceedingly small part of its orbit, so the elements are
- necessarily uncertain) this would put QB1 on the inner edge of the
- Kuiper Belt.
