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. It is a contact binary. Orbit The orbit of this potentially hazardous asteroid (PHA) has been well-established with 20 years of observations. It orbits from inside the orbit of Mercury out to the orbit of Mars. It makes close approaches to all of the inner planets. 2020 The asteroid came to perihelion on 13 October 2020 when it passed the Sun going 88 km/s km/h off us.speed The asteroid was not more than 60 degrees from the Sun until 26 November 2020 and was observed by Goldstone radar on 27 November 2020. On 29 November 2020 the asteroid passed 0.02876 AU e6km LD unit on from Earth. Even the 2018 orbit solution had a known accuracy of roughly ±150 km for the close approach. With the radar observations the close approach distance is known with an accuracy of roughly ±5 km. 2140 This asteroid will pass 0.00162 AU e3km LD unit on from Earth on 1 December 2140. 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 Jupiter Tisserand invariant, used to distinguish different kinds of orbits, is 6.228. Physical characteristics In the SMASS classification, the object's spectral type is that of an X-type. 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. Numbering and naming This minor planet was numbered by the Minor Planet Center on 2 April 2007. As of 2018, it has not been named. __NOTOC__ See also 2002 NY 40 2014 HQ 124 (388188) 2006 DP 14 (53319) 1999 JM 8 Notes speed v = 42.1219 1/r − 0.5/a, where r is the distance from the Sun, and a is the major semi-axis. Objects move fastest at perihelion and slowest at aphelion. References 30em 2020-11-28 last obs.
