51824 Mikeanderson (provisional designation 2001 OE30) is an Eoan asteroid in the outer region of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 19 July 2001, by astronomers of the Near-Earth Asteroid Tracking program at Palomar Observatory in California , United States . The asteroid was named for American astronaut and mission payload commander Mike Anderson, who died in the Space Shuttle Columbia disaster.[5]

Orbit and classification

Mikeanderson is a member the Eos family (606),[3] the largest asteroid family in the outer asteroid belt consisting of nearly 10,000 asteroids. It orbits the Sun in the outer main-belt at a distance of 2.7–3.3 AU once every 5 years and 3 months (1,903 days; semi-major axis of 3.01 AU). Its orbit has an eccentricity of 0.11 and an inclination of 10° with respect to the ecliptic.[1]

The body's observation arc begins with a precovery taken at Palomar Observatory in October 1960, more than 40 years prior to its official discovery observation.[5]

Physical characteristics

The asteroid's spectral type is unknown. Typically, members of the Eos family are K-type asteroids. Mikeanderson's measured albedo also agrees with this spectral classification (see below).[6]:23

Rotation period

As of 2017, no rotational lightcurve of Mikeanderson has been obtained from photometric observations. The asteroid's rotation period, poles and shape remain unknown.[1][7]

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Mikeanderson measures 4.969 kilometers in diameter and its surface has an albedo of 0.149.[4]

Naming

This minor planet was named after Michael P. Anderson (1959–2003), an American astronaut and payload commander of the Columbia Space Shuttle who was killed in the STS-107 reentry disaster on 1 February 2003. The approved naming citation was published by the Minor Planet Center on 6 August 2003 (M.P.C. 49283).[8]

The following asteroids were named in memory of the other six members of STS-107: 51823 Rickhusband, 51825 Davidbrown, 51826 Kalpanachawla, 51827 Laurelclark, 51828 Ilanramon and 51829 Williemccool.
