    2001 AV43 is a small asteroid that is a Near-Earth object and an Apollo asteroid.

    Orbit

    The orbit of 2001 AV43 has been well-established with over 13 years of observations. The asteroid was discovered January 5, 2001, but precovery images taken in August 2000 were found after its discovery. The orbit of 2001 AV43 is predicted to bring the asteroid within 0.002094 AU (313,300 km; 194,600 mi) of Earth on November 11, 2029.[2] For comparison, the distance to the Moon is about 0.0026 AU (384,400 km). The asteroid approached 2.7 lunar distances from the Earth on November 18, 2013, and the angle of approach made it a good target for radar observations.[4]

    The Jupiter Tisserand invariant, used to distinguish different kinds of orbits, is 5.017.[2] The orbit has a very low inclination of about 0.2 degrees.

    Physical characteristics

    An attempt to measure the rotation period using radar resulted in 0.17 hours, but this result is considered to be incomplete or inconclusive.[2]
