Re: The IAU have lost a planet! - that was darn careless...
You had me wondering if I was confusing reality and fantasy (again). I found this on the IAU website. (International Astronomers Union) (Are they in charge of Space.? That is an awesome responsibility) Now that we've talked about it, I think Nemesis is not only a mythological and fictional name but also a proposed name for a planet(oid).
If the proposed Resolution is passed, the 12 planets in our Solar System will be Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Charon and 2003 UB313. The name 2003 UB313 is provisional, as a "real" name has not yet been assigned to this object. A decision and announcement of a new name are likely not to be made during the IAU General Assembly in Prague, but at a later time. The naming procedures depend on the outcome of the Resolution vote. There will most likely be more planets announced by the IAU in the future. Currently a dozen "candidate planets" are listed on IAU's "watchlist" which keeps changing as new objects are found and the physics of the existing candidates becomes better known.
