(10551) Göteborg is an asteroid of the outer main belt , which was discovered on December 18, 1992 by the Belgian astronomer Eric Walter Elst at the Schmidt telescope of the French Observatoire de Calern near Grasse ( IAU code 010). Unconfirmed sightings of the asteroid had already given in January 1931 under the provisional designation 1931 AK at the Lowell Observatory in Arizona .
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. The ageless (not osculating ) orbital elements of (10551) Göteborg are almost identical with those of the smaller, if one of the absolute brightness starting from 14.6 to 12.1, asteroids (50951) 2000 GE 78 .
The rotation period of (10511) Göteborg was established in 2015 by Adam Waszczak, Chan-Kao Chang, Eran Ofek et al. examined. However, the light curves were not sufficient for a determination.
(10551) Gothenburg was named on March 2, 2000 after the Swedish city of Gothenburg .
