7330 Annelemaître           Discovered 1985 Oct. 15 by E. Bowell at the Anderson Mesa Station of the Lowell Observatory.
Named in honor of Belgian mathematician Anne Lemaître (b. 1957) for her pioneering analytic studies of the dynamics of minor planets in mean-motion resonances. She has also investigated the process of adiabatic capture into resonance, and has computed accurate proper elements for objects with large orbital eccentricities and inclinations. Name suggested and citation provided by A. Morbidelli.
