    51823 Rickhusband (provisional designation 2001 OY28) is a dark Lixiaohua asteroid from the outer regions of the asteroid belt, approximately 9 kilometers in diameter.

    Contents

    It was discovered on 18 July 2001, by astronomers of the Near-Earth Asteroid Tracking at Palomar Observatory in California, United States. [5] The asteroid was named after American astronaut Rick Husband, who died in the Space Shuttle Columbia disaster. [2]

    Orbit and classification

    Rickhusband is a member of the Lixiaohua family, an outer-belt asteroid family of more than 700 known members, which consists of C- and X-type asteroids. [3] [6] :23

    It orbits the Sun in the outer main-belt at a distance of 2.5–3.8  AU once every 5 years and 7 months (2,036 days). Its orbit has an eccentricity of 0.22 and an inclination of 12° with respect to the ecliptic. [1]

    The body's observation arc begins with its first identification as 1994 JM7 by Spacewatch at Kitt Peak Observatory in May 1994, more than 7 years prior to its official discovery observation by NEAT. [5]

    Physical characteristics

    Rotation period

    As of 2017, no rotational lightcurve of Rickhusband has been obtained from photometric observations. The asteroid's rotation period, poles and shape remains unknown. [7]

    Diameter and albedo

    According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Rickhusband measures 8.731 kilometers in diameter and its surface has an albedo of 0.048. [4]

    Naming

    This minor planet was named in memory of American astronaut Rick Husband (1957–2003), who was the commander of STS-107 and was killed in the Space Shuttle Columbia disaster on 1 February 2003. The official naming citation was published by the Minor Planet Center on 6 August 2003 ( M.P.C. 49283). [8]
