, provisional designation , is a centaur and damocloid orbiting the Sun with a very high inclination of almost 80ð. It was discovered on 18 December 2004 by the Siding Spring Survey at the Siding Spring Observatory in Australia. The critical and unusual object measures approximately in diameter.
It orbits the Sun at a distance of 3.6âÂÂ12.8 AU once every 23 years and 4 months (8,520 days; semi-major axis of 8.16 AU). Its orbit has an eccentricity of 0.57 and an inclination of 79ð with respect to the ecliptic. The body's observation arc begins with its official discovery observation at the Siding Spring Observatory in December 2004.
Johnston's Archive assumes a standard albedo of 0.09 and calculates a diameter of 12 kilometers based on an absolute magnitude of 12.9.
