Template: Infobox Asteroid / Maintenance / Error 1

( 2191 ) Uppsala is an asteroid of the outer main belt, which was discovered by the Swedish astronomer Claes -Ingvar Lagerkvist on August 6, 1977 at 50 -cm Schmidt telescope of the Astronomical Observatory of Uppsala. The telescope was from 1957 to 1982 at the Mount Stromlo Observatory ( IAU code 414) at Mount Stromlo in Canberra, Australia.

Unconfirmed sightings of the asteroid it had on 15 November 1925 ( with the provisional designation 1925 VL) given at the Heidelberg State Observatory king chair, on 26 November 1957 ( 1957 WJ2 ) at Lowell Observatory in Arizona, and on 5 September 1972 ( 1972 RP3 ) at the Crimean Observatory in Nautschnyj.

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.

( 2191 ) Uppsala has a mean diameter of 17.54 km ( ± 1.3 ). Its albedo of 0.1734 (± 0.029) is comparable to that of Mars (0.15 ).

The asteroid was named after the Swedish city of Uppsala on April 1, 1980, and the University of Uppsala, the oldest existing university in Scandinavia.
