(5748) Davebrin is an asteroid of the main middle belt discovered on February 19, 1991 by the American astronomer Eleanor Helin at the Palomar Observatory ( IAU code 675) in California . It had unconfirmed sightings of the asteroid on April 26, 1952 (1952 HE 3 ) at the McDonald Observatory in Texas and on March 15, 1983 (1983 EL 4 ) at the Crimean Observatory in Nautschnyj and on September 25 and 26, 1989 ( 1989 SK 9 ) at the Chilean La Silla Observatory .
(5748) Davebrin belongs to the Eunomia family, a group named after (15) Eunomia which is believed to include five percent of the main belt asteroids. The timeless (non- osculating ) orbital elements of (5748) Davebrin are almost identical to those of the two smaller ones, assuming the absolute magnitude of 16.5 and 16.0 compared to 13.7, asteroids (132432) 2002 GG 160 and ( 150975) 2001 TV 196 .
The asteroid is in a 7-3-2 orbital resonance with Saturn and Jupiter , that is, with seven orbits of (5748) Davebrin around the Sun , Jupiter has three orbits and Saturn has two.
The asteroid was on 26 February 1994, after the US science fiction - author and astrophysicist David Brin named.
