(2910) Yoshkar-Ola is an asteroid of the main inner belt , which was discovered by the Soviet astronomer Nikolai Tschernych on October 11, 1980 at the Crimean Observatory in Nautschnyj ( IAU code 095). There had already been several unconfirmed sightings of the asteroid: on October 25, 1957 under the provisional designation 1957 UD at the State Observatory Heidelberg-Königstuhl and in April 1979 (1979 HL) at the Cerro Tololo Inter-American Observatory in Chile .
Mean solar distance ( major semi-axis ), eccentricity and inclination of the orbit plane of the asteroid are similar to the orbital data of the members of the Flora family, a large group of asteroids named after (8) Flora . Asteroids of this family move in a 4: 9 orbital resonance with the planet Mars around the sun . The group is also called the Ariadne family, after the asteroid (43) Ariadne .
In the PSABA project of the Czech astronomer Petr Pravec , an investigation of the light curve of (2910) Yoshkar-Ola was recommended. Astronomers in Australia ( Julian Oey ) and Slovakia (Jozef Világi, Štefan Gajdoš, Leonard Kornoš and Adrián Galád ) then examined the asteroid in September and October 2006 and determined a rotation period of 3.4233 (± 0.0001) hours.
The asteroid was named on November 8, 1984 after the city of Yoshkar-Ola on the occasion of its 400th anniversary. At the time the asteroid was named, Yoshkar-Ola was the capital of the Mari ASSR , then the capital of the Mari El Republic in Russia .
