Шаблон:Mp, provisional designation Шаблон:Mp, is an asteroid on an eccentric orbit, classified as near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 2.5 kilometers in diameter. It was discovered on 13 November 2002, by astronomers of the Near-Earth Asteroid Tracking program at Palomar Observatory in California, United States.[1] It is one of the largest potentially hazardous asteroids known.[2]

Orbit and classification

Шаблон:Mp is a member of the dynamical Apollo group,[3][1] which are Earth-crossing asteroids. Apollo asteroids are the largest subgroup of near-Earth objects. It orbits the Sun at a distance of 0.9–3.4 AU once every 3 years and 1 month (1,138 days; semi-major axis of 2.13 AU). Its orbit has an eccentricity of 0.58 and an inclination of 9° with respect to the ecliptic.[3]

The body's observation arc begins with a precovery from the Digitized Sky Survey taken at the Palomar Observatory in October 1955, or 47 years prior to its official discovery observation.[1]

Close approaches

With an absolute magnitude of 15.3, Шаблон:Mp is one of the brightest and largest known potentially hazardous asteroid (see PHA-list).[2] It has an Earth minimum orbital intersection distance of Шаблон:Convert, which translates into 11.7 lunar distances.[3] On 18 May 2092, the body will make its closest near-Earth encounter at a nominal distance of 0.095 AU (37 LD).[3] The asteroid is also Mars-crosser, crossing the orbit of the Red Planet at 1.66 AU.

Physical characteristics

Шаблон:Mp is an assumed, stony S-type asteroid.[4]

Rotation period

In 2014 and 2017, several rotational lightcurvesШаблон:Efn of Шаблон:Mp were obtained from photometric observations by American astronomer Brian Warner at the Palmer Divide Station (Шаблон:Small) in California.[5][6][7]Шаблон:Efn Lightcurve analysis gave a consolidated rotation period of 7.879 hours with a brightness amplitude between 0.31 and 0.64 magnitude (Шаблон:Small).[4]Шаблон:Efn

In 2017, Warner also modeled the photometric data and determined a sidereal period of 7.878512 hours, as well as a spin axis of (73.0°, −50.0°) in ecliptic coordinates (λ, β).[4]

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Шаблон:Mp measures 2.233 kilometers in diameter and its surface has an albedo of 0.294,[8] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20, and calculates a diameter of 2.59 kilometers based on an absolute magnitude of 15.3.[4]

Numbering and naming

This minor planet was numbered by the Minor Planet Center on 30 August 2004.[9] As of 2018, it has not been named.[1]
