(394130) 2006 HY51 is an outstandingly eccentric asteroid and near-Earth object of the Apollo group, approximately 1.2 kilometers in diameter. It was discovered by LINEAR at Lincoln Lab's ETS on 26 April 2006.[2][4]

The asteroid orbits the Sun at a distance of 0.1–5.1 AU once every 4 years and 2 months (1,530 days). Its orbit has an eccentricity of 0.97 and an inclination of 31° with respect to the ecliptic.[3]

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 0.0905 AU (13,500,000 km), equivalent to 35.2 lunar distances.[3]

As of 2016, the asteroid's effective size, its composition and albedo, as well as its rotation period and shape remain unknown.[3]
