(8201) 1994 AH2

Orbit and classification

The asteroid orbits the Sun at a distance of 0.7–4.3 AU once every 4.04 years (1,477 days). Its orbit has an eccentricity of 0.71 and an inclination of 10° with respect to the ecliptic. It is a member of the Alinda group of asteroids with a 3:1 resonance with Jupiter that has excited the eccentricity of the orbit over the eons. As an Alinda asteroid it makes approaches to Jupiter, Earth, and Venus.

has an Earth minimum orbital intersection distance of 0.1012 AU, which corresponds to 39.4 lunar distances. Due to its elongated orbit, it also approaches the orbit of Jupiter within 0.1022 AU. On 4 January 2079, it will pass 0.3595 AU from the Earth.

A first precovery was taken at the discovering observatory in 1981, extending the asteroid's observation arc by 13 years prior to its discovery.

Physical characteristics

In the SMASS classification, is characterized as a rare O-type asteroid.

Rotation period

In the late 1990s, Czech astronomer Petr Pravec obtained two rotational lightcurves for this asteroid from photometric observations taken at the Ondřejov Observatory, Czech Republic. They gave a longer-than average rotation period of and 24 hours with a brightness variation of 0.27 and 0.3 magnitude, respectively ().

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 1.86 kilometers in diameter and its surface has an albedo of 0.154. The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.18 and calculates a diameter of 2.17 kilometers, based on an absolute magnitude of 15.8. American astronomer Richard Binzel gives a diameter of 2.2 kilometers.

Naming

As of 2017, remains unnamed.
