( 51825 ) David Brown is an asteroid of the outer main belt, which was discovered on 19 July 2001 by the American astronomer Eleanor Helin, on shots of the project Near Earth Asteroid Tracking ( NEAT), with the 120 - inch Oschin Schmidt telescope of the Palomar Observatory (IAU code 644 ) in California had been made. Unconfirmed sightings of the asteroid had previously existed for a CZ14 on 8 and 10 February 1994 under the provisional designation 1994 at the La Silla Observatory of the European Southern Observatory in Chile, and on 10 and 13 February 1999 ( 1999 CO55 ) at Lincoln Laboratory experimental Test system in Socorro, New Mexico.

The asteroid is part of the Eos family, a group of asteroids, which typically have semi-major axes from 2.95 to 3.1 AE, bounded on the inside of the Kirkwood gap in the 7:3 resonance with Jupiter, and orbital inclinations between 8 ° and 12 degrees. The group is named after the asteroid (221 ​​) Eos. It is believed that the family was created over one billion years ago by a collision. The timeless ( nichtoskulierenden ) orbital elements of ( 51825 ) David Brown are almost identical with those of the possibly slightly smaller, if we start from the absolute brightness of 14.2 against 14.1, asteroid ( 86124 ) 1999 RK147.

( 51825 ) David Brown was named on 6 August 2003 by the U.S. astronauts David McDowell Brown, who came as a mission specialist and pilot of Space Shuttle Columbia on 1 February 2003 in the crash of their lives. After all members of the Columbia crew asteroids were named: by Rick Douglas Husband ( 51823 ) Rickhusband, by Michael Philip Anderson ( 51824 ) Mike Anderson, according to Kalpana Chawla ( 51826 ) Kalpanachawla, to Laurel Blair Salton Clark ( 51827 ) Laurelclark, Ilan Ramon ( 51828 ) Ilanramon and after William Cameron McCool ( 51829 ) Williemccool.
