(8640) Ritaschulz is an asteroid of the main middle belt discovered on November 6, 1986 by the American astronomer Edward LG Bowell at Anderson Mesa Station ( IAU code 688) of the Lowell Observatory in Coconino County , Arizona .
Mean distance from the Sun ( major semiaxis ), eccentricity and inclination of the orbit plane of the asteroid roughly correspond to the Dora family, a group of asteroids named after (668) Dora . However, Dora asteroids have a rather dark surface and are spectroscopically C and Ch asteroids. According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), however, a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (8640) Rita assumed a light surface, so it could, roughly speaking, be be an S-asteroid.
(8640) Ritaschulz was named after the German astrophysicist Rita Schulz on May 23, 2000 at the suggestion of the astronomer Maria A. Barucci .
