(7333) Bec-Borsenberger Main-belt Asteroid

Discovered on 29 September 1987 by E. Bowell at Anderson Mesa.

Named in honor of Annick Bec-Borsenberger (b. 1940), astronomer at the Bureau des Longitudes, Institut de Mécanique Céleste de l´Observatoire de Paris. Bec-Borsenberger is well known for her analytical theory of the motion of the moon. She is an expert in the dynamics of small bodies, particularly in the convergence of algorithms used to determine perturbed orbits. She helped analyze Hipparcos data on minor planets and satellites and has been involved in the ISO mission. Citation provided by M. A.
