(8201) 1994 AH2 is a highly eccentric, rare-type

AANEAS survey at the Siding Spring Observatory, Australia.[7] It has an Earth minimum orbit intersection distance of 0.1 AU (15 million km) and is associated with the Beta Taurids daytime meteor shower.[8]

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.[1] 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.[9] As an Alinda asteroid it makes approaches to Jupiter, Earth, and Venus.[10]

1994 AH2 has an Earth

lunar distances. Due to its elongated orbit, it also approaches the orbit of Jupiter within 0.1022 AU (15,300,000 km).[1] On 4 January 2079, it will pass 0.3595 AU (53,800,000 km) from the Earth.[10]

A first precovery was taken at the discovering observatory in 1981, extending the asteroid's observation arc by 13 years prior to its discovery.[7]

Physical characteristics

In the

SMASS classification, 1994 AH2 is characterized as a rare O-type asteroid.[1]

Rotation period

In the late 1990s, Czech astronomer

U=2/n.a.).[6][a]

Diameter and albedo

According to the survey carried out by the

Richard Binzel gives a diameter of 2.2 kilometers.[5]

Naming

As of 2017, 1994 AH2 remains unnamed.[7]
