(7456) Doressoundiram Main-belt Asteroid

Discovered on 17 July 1982 by E. Bowell at Anderson Mesa.

Named in honor of Alain Doressoundiram (b. 1968), French planetary scientist. Doressoundiram has worked on the collisional evolution of the population of minor planets, in particular the formation and evolution of binary systems during a family-forming collision. He has contributed to the spectroscopic characterization of a number of minor planet families and helped plan the Rosetta and DS4-Champollion space missions.
