Шаблон:Infobox planet

Шаблон:Mp, provisional designation Шаблон:Mp, is a trans-Neptunian object and damocloid from the outer Solar System. Its orbit is retrograde and comet-like, and has a high eccentricity. It was discovered on 4 September 2002 by astronomers with the LONEOS survey at Anderson Mesa Station, Arizona, in the United States. The unusual object measures approximately Шаблон:Convert in diameter and is likely elongated in shape. It is a slow rotator and potentially a tumbler as well.[1] The object was probably ejected from the ecliptic by Neptune.Шаблон:Citation needed

Orbit and classification

Шаблон:Mp is a member of the damocloids,[2] with a retrograde orbit and a negative TJupiter of −0.8340. It is also a trans-Neptunian object, as its orbit has a semi-major axis larger than that of Neptune (30.1 AU).[3] The Minor Planet Center lists it as a critical object, centaur, and (other) unusual minor planet due to an orbital eccentricity of more than 0.5.[4]

It orbits the Sun at a distance of 2.5–105 AU once every 396 years (semi-major axis of 53.92 AU). Its orbit has an eccentricity of 0.95 and an inclination of 119° with respect to the ecliptic.[3] The body's observation arc begins with a precovery taken by Astrovirtel Шаблон:Obscode at ESO's La Silla Observatory in February 2001, or 19 months prior to its official discovery observation at Anderson Mesa.[5]

Numbering and naming

This minor planet was permanently numbered Шаблон:LoMP by the Minor Planet Center on 14 June 2003 (Шаблон:Small).[6] As of 2018, it has not been named.[5]

Physical characteristics

The object has a B–R magnitude of 1.37,[2] typical for most dynamical groups in the outer Solar System.

Rotation period

In October 2010, a rotational lightcurve of Шаблон:Mp was obtained from photometric observations by French amateur astronomer René Roy . Lightcurve analysis gave a rotation period of 200 hours with a brightness amplitude of 0.6 magnitude, indicative of an elongated, non-spherical shape (Шаблон:Small).[7] With a rotation period above 100 hours, it is a typical slow rotator.

Diameter and albedo

According to the survey of minor-planet albedos of bodies in a comet-like orbit, carried out by Yanga Fernández in collaboration with David Jewitt and Scott Sheppard at the Institute for Astronomy, Hawaii, Шаблон:Mp measures 14.6 kilometers in diameter and its surface has an albedo of 0.098.[3][8] Johnston's archive gives a rounded figure of 15 kilometers.[2]
