(3232) Brest is an asteroid of the main outer belt , which was discovered by the Soviet astronomer Lyudmila Tschernych on September 19, 1974 at the Crimean Observatory in Nautschnyj ( IAU code 095).
There had already been several unconfirmed sightings of the asteroid: on April 5, 1946 (1946 GE) at the Union Observatory in Johannesburg , on March 5, 1951 (1951 ER) and on November 4, 1964 (1964 VN) at the Goethe-Link- Observatory in Indiana and in October 1969 (1969 TS 5 ) at the Crimean Observatory in Nautschnyj.
The asteroid belongs to the Eos family, a group of asteroids, which typically have large semiaxes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap of the 7: 3 resonance with Jupiter , and orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago.
(3232) Brest was named on July 11, 1987 after the Belarusian city of Brest .
