(3231) Mila is an asteroid of the main inner belt that was discovered by the Soviet astronomer Lyudmyla Shuravlowa on September 4, 1972 at the Crimean Observatory in Nautschnyj ( IAU code 095). There had already been several unconfirmed sightings of the asteroid: including on August 21, 1949 (1949 QJ 1 ), August 27, 1949 (1949 QN 1 ) and March 14, 1955 (1955 EL) at the Goethe Link Observatory in Indiana .
Mean distance from the Sun ( major semiaxis ), eccentricity and inclination of the orbit plane of the asteroid roughly correspond to the Vesta family , a large group of asteroids named after (4) Vesta , the second largest asteroid and third largest celestial body in the main belt. According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (3231) Mila assumed a dark surface, so it could, roughly speaking, be around trade a C asteroid . David J. Tholen came to the same conclusion in 1994.
(3231) Mila was named on May 31, 1988 after the Soviet figure skater Lyudmila Alexejewna Pachomowa (1946–1986), who was world champion , European champion and Olympic champion in ice dancing . The Martian crater Mila, however, was named after the Algerian city Mila in 1976 .
