2001 AV43 is a very small, monolithic

lunar distance (LD) and will approach Earth at 0.81 LD on 11 November 2029.[2]

Orbit and classification

2001 AV43 is a member of the dynamical

aphelion is smaller than the orbit of the Red Planet at 1.66 AU.[2]

This asteroid orbits the Sun at a distance of 0.97–1.59 

semi-major axis of 1.28 AU). Its orbit has an eccentricity of 0.24 and an inclination of 0° with respect to the ecliptic.[2] The body's observation arc begins with a precovery found in ESO's Astrovirtel data archive (I03), in August 2000, less than 5 months prior to its official discovery observation at Socorro.[1]

Close approaches

2001 AV43 has an Earth

potentially hazardous asteroid.[2]

On 18 November 2013, the asteroid passed Earth at 2.7 LD. The angle of approach made it a good target for radar observations.[5]

On 11 November 2029, the orbit of 2001 AV43 is predicted to bring the asteroid within a nominal distance of 0.00209 AU (313,000 km; 194,000 mi) or 0.81 LD of Earth. It will also pass the Moon at an even shorter nominal distance of 0.00166 AU (248,000 km; 154,000 mi)[2]

Physical characteristics

2001 AV43 is an assumed stony S-type asteroid.[3]

Rotation period

A rotational

U=2).[3][4] With such a short period, it is a notable fast rotator. The observers classified it as a "monolithic fast-rotating asteroid" (MFRA).[4]

Diameter and albedo

The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and derives a diameter of 0.03 kilometers based on an absolute magnitude of 24.9.[3]

Numbering and naming

As of 2018, this minor planet has neither been numbered nor named.[1]
