(153201) 2000 WO107

(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]

OrbitEdit

The orbit of this potentially hazardous asteroid (PHA) has been well-established with over 14 years of observations. This asteroid is predicted to pass within 0.001629 AU (243,700 km) of the Earth in the year 2140.[1] 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 characteristicsEdit

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 namingEdit

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