Nicolas Rambaux (b. 1976) is a French dynamicist working on the internal structure, the rotation and tidal evolution of many solar system objects: the Moon, the Martian satellites Phobos and Deimos, main-belt asteroids, trans-Neptunian objects (Pluto, Haumea, Quaoar), among others. Nicolas is also part of a working group for the ESA mission Hera.Naming citation (WGSBN Bull. 6, #11, 30), IAU / Minor Planet Center, via NASA/JPL
