(394130) 2006 HY51 is a near-Earth object of the Apollo asteroid group with a high orbital eccentricity, approximately 1.2 kilometers in diameter. It was discovered on 26 April 2006, by LINEAR at Lincoln Lab's ETS in Socorro, New Mexico, United States. [2]
2006 HY51 orbits the Sun at a distance of 0.1–5.1 AU once every 4 years and 2 months (1,527 days). Its orbit has an eccentricity of 0.97 and an inclination of 33° with respect to the ecliptic. [1]
It is the asteroid with the third-smallest known perihelion of any known object orbiting the Sun.[ citation needed ] Its extreme orbital eccentricity brings it within 0.081 AU of the Sun (26% of Mercury's perihelion) and as far as 5.118 AU from the Sun (making it a Jupiter-grazer). It has a minimum orbit intersection distance with Earth of 0.1064 AU (15,900,000 km), equivalent to 41.5 lunar distances. [1]
Any small bodies with even more eccentric orbits are likely to suffer a rotational breakup by the age comparable to that of the Solar System, although 2006 HY51 itself is not expected to break. [4]
According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, 2006 HY51 measures 1.218 kilometers in diameter and its surface has an albedo of 0.157. [3] The asteroid's composition and shape, as well as its rotation period remain unknown. It has an absolute magnitude of 17.2. [1]
As of 2017, this minor planet remains unnamed. [2]
