Size
Observations of thermal emissions by the Spitzer Space Telescope in 2007 give a diameter of 734Template:± km[1] and an albedo of 0.117Template:±.[1]
Surface
ESO analysis of spectra reveals a strong red slope and no presence of water ice (in contrast to Quaoar, also red) suggesting organic material (see comparison of colours and typical composition inferred from spectra of the TNOs).
