1146 Biarmia is a main belt asteroid orbiting the Sun. Approximately 31 kilometers in diameter, it makes a revolution around the Sun once every 5 years. It was discovered by Grigory Nikolaevich Neujmin on May 7, 1929.[1] After being assigned a provisional designation of 1929 JF, it was named after a legendary country Bjarmland in northern Russia near the Finnish border.[2]
Photometric observations of this asteroid collected during 1999 show a rotation period of 11.514 ± 0.004 hours with a brightness variation of 0.32 magnitude.[3]
