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 . 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 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 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.
