(3344) Modena is an asteroid of the main inner belt discovered on May 15, 1982 at the San Vittore Observatory ( IAU code 552) in Bologna .
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 (3344) Modena determined that it could be one of the rare V-asteroids .
Adrián Galád and Bill Gray have calculated that (3344) Modena in its orbit around the sun to the dwarf planet (1) Ceres in the examined period from November 6, 1967 to September 13, 2023 on September 27, 1980 to 0.021136 astronomical units ( approx. 3 million kilometers), which could have had an impact on the orbit of the asteroid and which could have helped determine the mass of (1) Ceres, if it had been investigated at the time of closest approach.
(3344) Modena was named on March 26, 1986 after the city of Modena , which is about 40 kilometers west of Bologna. The naming text refers to the Cathedral of Modena , the tower of the cathedral (Torre Ghirlandina ) and the Castello Estense . Modena was also home to the astronomers Geminiano Montanari (after whom the asteroid of the main outer belt (8421) was named Montanari ), Giovanni Battista Amici (after whom the asteroid of the main middle belt (3809) was named Amici ), Giuseppe Bianchi and Ermes Colombini ( * 1956).
