? only 12? In your other post, you stated that they considered this size to be around 850 km. So in addition to the current 9, I assume you would have 2003 UB313, Ceres, and Sedna, at least. But I seem to recall several other currently known bodies in the Kuiper Belt larger than 850 km across, such as Quaoar, 2005 FY9, and 2003 EL61 as well as perhaps 2002 TC302.
I am very happy to see that the definition has some basis in the physical nature of the body and not some arbitrary cutoff, like 2000 km. While it may take some time for people to accept that Ceres will now be called a planet, I am glad that this whole non-sense is finally nearing an end and we can all get on with our lives. EDIT: Okay, I think we can all agree that Charon is not a planet... -------------------- &@^^!% Jim! I'm a geologist, not a physicist!
