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.
