Шаблон:Infobox planet

Шаблон:Mp, provisional designation Шаблон:Mp, is a sub-kilometer asteroid on an eccentric orbit, classified as a near-Earth object and potentially hazardous asteroid of the Apollo group, approximately Шаблон:Convert in diameter. It was discovered on 31 December 2007, by astronomers of the Catalina Sky Survey conducted at the Catalina Station in Arizona, United States.[1]

Orbit and classification

Шаблон:Mp is an Apollo asteroid that crosses the orbit of Earth.[1][2] Apollo's are the largest group of near-Earth objects with nearly 10 thousand known members.[3]

It orbits the Sun at a distance of 0.60–2.55 AU once every 2 years (722 days; semi-major axis of 1.58 AU). Its orbit has a high eccentricity of 0.62 and an inclination of 6° with respect to the ecliptic.[2] This makes it also a Mars-crossing asteroid, as it crosses the orbit of the Red Planet at 1.66 AU, as well as a Venus-crosser due to its aphelion of less than 0.71 AU. The body's observation arc begins at Catalina with its official discovery observation in December 2007.[1]

Close approaches

Шаблон:Mp has a minimum orbital intersection distance (MOID) with Earth of Шаблон:Convert, which corresponds to 1.83 lunar distances (LD).[2] It has an absolute magnitude of 21.0. This makes it a potentially hazardous asteroid,[1][2] which are defined as having a MOID of less than Шаблон:Convert and an absolute magnitude brighter than 22. Besides Earth, it also makes close approaches to Venus, Mars and the Moon.[2]

On 26 December 2007, five days prior to its discovery observation, it passed Earth at a nominal distance of Шаблон:Convert. On 2 January 2101, it is predicted to flyby Earth at Шаблон:Convert and pass the Moon at a similar distance five hours earlier as well (also see Шаблон:Section link).[2]

Physical characteristics

The body's spectral type is unknown. Near-Earth asteroids are often of a stony composition.

Diameter and albedo

Based on a generic magnitude-to-diameter conversion, Шаблон:Mp measures Шаблон:Convert in diameter, for an absolute magnitude of 21.0, and an assumed albedo of 0.20 and 0.057, which represent typical values for stony and carbonaceous asteroids, respectively.[4]

Rotation period

As of 2018, no rotational lightcurve of Шаблон:Mp has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown.[2]

Numbering and naming

This minor planet was numbered by the Minor Planet Center on 22 February 2016 (Шаблон:Small).[5] As of 2018, it has not been named.[1]
