(20000) Varuna

(20000) Varuna = 2000 WR106 is the third largest Trans-Neptunian Object, with an absolute magnitude of 3.7. It was discovered on November 28th 2000 with the SpaceWatch Telescope at Kitt Peak. The orbit is based on 41 observations at 6 oppositions since 1954, when it was imaged in the Palomar Observatory Sky survey. The location of various other "pre-covery" images has allowed a high-quality orbit to be calculated. The semi-major axis is 43.27AU and the excentricity 0.053. With a period of 285 this object is classed as a "Cubewanian" after the prototype object 1992 QB1.
