(239675) Mottez Main-belt Asteroid
Discovered on 26 December 2008 by B. Christophe at Saint-Sulpice.
Fabrice Mottez (b. 1963) works on plasma astrophysics at the Paris Observatory. His work has contributed to the physics of Earth's polar auroras, to radio emissions of solar-system planets and satellites, as well as pulsars and their electromagnetic interaction with orbiting companions, including asteroids.Naming citation (MPC batch dated 2014-09-09), IAU / Minor Planet Center, via NASA/JPL
