(8498) Ufa is an asteroid of the outer main belt that was discovered by the Ukrainian - Soviet astronomer Lyudmyla Shuravlowa on September 15, 1990 at the Crimean Observatory in Nautschnyj ( IAU code 095). Unconfirmed sightings of the asteroid had already occurred on February 18 and 19, 1977 (1977 DL 5 ) at the Japanese Kiso Observatory and on February 20 and 21, 1982 (1982 DE 2 ) at the Kleť Observatory near Český Krumlov .
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 timeless (non- osculating ) orbit elements of (8498) Ufa are almost identical to those of the smaller, if one assumes the absolute brightness of 16.6 compared to 12.7, asteroids (216812) 2006 TA 118 .
(8498) Ufa was named after Ufa on January 24, 2000 , the capital of the Russian Republic of Bashkortostan .
