(2889) Brno

Template: Infobox Asteroid / Maintenance / Error 1

( 2889 ) Brno is one of the major outer asteroid belt, which by the Czech astronomer Antonín Mrkos on Kleť Observatory (IAU code 046) was discovered near Český Krumlov on 17 November 1981. Unconfirmed sightings of the asteroids were previously in May 1953 (1953 JE) at the Goethe Link Observatory, Indiana, on 15 April 1958 (1958 GE ) on the Heidelberg State Observatory King chair, and on September 30, 1970 ( 1970 SF1) and on 28 October 1976 ( 1976 UO4 ) at Crimean Observatory in Nautschnyj.

The rotation period of ( 2889 ) Brno was determined by René Roy at the observatory Geneva on November 10, 2012 provisionally with 9.51 hours. However, due to insufficient data this information has a margin of error of 30 percent.

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 ( 2889 ) Brno are almost identical to those of the two smaller, if we start from the absolute brightness of 14.8 and 15.7 against 11.3, asteroid ( 116882 ) 2004 FO118 and ( 214821 ) 2006 VJ16.

( 2889 ) Brno is named after the city of Brno ( Czech Brno). The appointment was made by the International Astronomical Union ( IAU) on 29 November 1993.
