(51823) Rickhusband is an asteroid of the outer main belt , which was discovered on July 18, 2001 by the American astronomer Eleanor Helin , on recordings of the Near Earth Asteroid Tracking (NEAT) project taken with the 120 cm Oschin-Schmidt Telescope of the Palomar Observatory ( IAU code 644) in California .
Rickhusband is part of the Gantrisch family . This group of asteroids was previously called the Lixiaohua family until (3330) Gantrisch was assigned to the group, which, with its 35 km diameter, replaced the 20 km large (3556) Lixiaohua as the largest member of this family. Sometimes the old family name is still used. It is an asteroid family with relatively chaotic orbital parameters seen over a long period of time, since large minor planets in the vicinity of the family (or their orbits around the sun , which intersect the orbits of the family members) such as (1) Ceres , (2) Pallas , (4) Vesta , (10) Hygiea , (52) Europa , (511) Davida and (704) Interamnia influence the orbits of family members and the family is therefore within the sphere of influence of several orbital resonances.
(51823) Rickhusband was named on August 6, 2003 after the American astronaut Rick Douglas Husband , who was killed in the accident on the space shuttle Columbia on February 1, 2003. Asteroids were named after all members of the Columbia crew: after Michael Philip Anderson (51824) Mikeanderson , after David McDowell Brown (51825) Davidbrown , after Kalpana Chawla (51826) Kalpanachawla , after Laurel Blair Salton Clark (51827) Laurelclark , after Ilan Ramon (51828) Ilanramon and after William Cameron McCool (51829) Williemccool .
