Named in memory of Michèle Moons (1951-1998), well known for her work on celestial mechanics done at the department of mathematics of Facultés Universitaires N. D. de la Paix, Namur, Belgium. She was assistant editor of the journal Celestial Mechanics and Dynamical Astronomy for nearly ten years. In the early 1980s she developed an analytical theory of the libration of the moon that is widely used by several centers interested in analyzing the moon's motion. Her later work included studies on the effects of resonant motion in the minor planet belt. Her early death is a great loss to her family and to science. Citation prepared by J. Henrard and J. Schubart, the name being suggested by the latter.
