イクシオン (小惑星)
1. 28978 Ixion28978 Ixion is a plutino . It is considered very likely to be a dwarf planet, although the IAU has not officially classified it as such. Light-curve-amplitude analysis shows only small deviations, which suggests that Ixion is a spheroid with small albedo spots and hence a dwarf planet. Tancredi (2010) thinks that Ixion is a very probable plutoid. Its diameter of 650 km estimated by Spitzer makes it about the fifth largest plutino.
