(55737) Coquimbo is an asteroid located in the main inner belt . It was discovered on February 11, 1988 by the Belgian astronomer Eric Walter Elst at the La Silla Observatory of the European Southern Observatory in Chile ( IAU code 809).
The mean diameter of the asteroid was calculated to be 3.241 km (± 0.114).
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), (55737) Coquimbo in a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel, subdividing all the asteroids examined into C, S and V types assigned to the S asteroids .
Mean distance from the Sun ( major semiaxis ), eccentricity and inclination of the orbital plane of (55737) Coquimbo 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.
(55737) Coquimbo was named on May 29, 2018 after the Chilean port city of Coquimbo , which is about 200 km south of the La Silla Observatory.
