11895 Dehant           Discovered 1991 Apr. 8 by E. W. Elst at the European Southern Observatory.
Véronique Dehant (b. 1959) is head of the section for time, earth rotation and space geodesy at the Royal Observatory, Uccle. She is currently involved with the NEIGE project, which plans a soft landing of a geodetic instrument on Mars. In 1999 she was awarded the Bomford prize for her work on the earth's nutation.
