Notes.
Diameter computed using an assumed geometric albedo of 0.7, with the exception of Haumea, whose diameter is taken from Lellouch et al. (2010). 2002 TX300 has a diameter measurement of 286 km and albedo of 88% (Elliot et al. 2010), but these are inconsistent with the given H magnitude.
Density computed assuming a Jacobi ellipsoid shape with a DP rotation period (see text for details).
