Шаблон:Mp is a sub-kilometer asteroid, classified as near-Earth object and potentially hazardous asteroid of the Aten group, approximately Шаблон:Convert in diameter. It was discovered on 6 December 1994, by Scottish–Australian astronomer Robert McNaught at Siding Spring Observatory in Australia.[1] It was one of the first asteroids discovered to have a semi-major axis less than Venus.Шаблон:Citation needed

Orbit and classification

Шаблон:Mp orbits the Sun at a distance of 0.3–1.0 AU once every 0 years and 7 months (201 days). Its orbit has an eccentricity of 0.53 and an inclination of 28° with respect to the ecliptic.[2] No precoveries were taken, and no prior identifications were made. The body's observation arc begins with its official discovery observation.[1]

Close encounter

The asteroid has an Earth minimum orbital intersection distance of Шаблон:Convert, which translates into 14.2 lunar distances.[2] It passed Шаблон:Convert from Earth on 6 December 1994.[3] On 4 December 2044, it will pass again at Шаблон:Convert from Earth.[3]

Physical characteristics

Шаблон:Mp has not been observed by any of the space-based surveys such as the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission. Based on a generic magnitude-to-diameter conversion, Шаблон:Mp measures approximately 0.2 kilometers in diameter assuming an albedo of 0.20, which is a typical value for stony S-type asteroids.[4]

As of 2017, no rotational lightcurve of this object has been obtained. The body's rotation period, shape and poles remain unknown.[5]

Naming and numbering

After its first observation in 1994, this minor planet was numbered 23 years later by the Minor Planet Center on 12 January 2017 (Шаблон:Small),[6]Шаблон:Rp after its last observation with the LCO–A 1-meter global telescope station at Sutherland, South Africa, on 6 December 2016 Шаблон:Obscode. As of 2018, the asteroid has not been named .[1][2]
