(153201) 2000 WO107 is a sub-kilometer asteroid, classified as near-Earth object and potentially hazardous asteroid of the Aten group.[1] It was discovered on 29 November 2000, by astronomers of the Lincoln Near-Earth Asteroid Research (LINEAR) at the Lincoln Laboratory's Experimental Test Site near Socorro, New Mexico, in the United States.[2]

Orbit

The orbit of this potentially hazardous asteroid (PHA) has been well-established with over 17 years of observations. This asteroid will pass 0.00162 AU (242 thousand km; 0.63 LD) from Earth on 1 December 2140.[1] The 2140 close approach distance is known with an accuracy of roughly ± 1000 km. For comparison, the distance to the Moon is about 0.0026 AU (384,400 km). The asteroid also appear on the list of PHA close approaches issued by the Minor Planet Center.[4]

The Jupiter Tisserand invariant, used to distinguish different kinds of orbits, is 6.228.[1]

Physical characteristics

In the SMASS classification, the object's spectral type is that of an X-type.[1][6] According to the space-based survey by NASA's NEOWISE mission, the asteroid measures 510 meters in diameter and its surface has an albedo of 0.129.[3]

Numbering and naming

This minor planet was numbered by the Minor Planet Center on 2 April 2007.[7] As of 2018, it has not been named.[2]
