    Orbit and classification

    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. 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]

    The 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]

    Physical characteristics

    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]

    Naming

    As of 2017, this minor planet remains unnamed.[2]
