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