(20435) Juliendewit Main-belt Asteroid
Discovered on 19 March 1999 by LINEAR at Socorro.
Julien de Wit (b. 1988) is a Belgian planetary scientist and associate professor at the Massachusetts Institute of Technology. By taking advantage of long-stare JWST images, he used serendipitous discovery and tracking of decameter-sized asteroids to model asteroid collisional processes at sub-kilometer scales.Naming citation (WGSBN Bull. 6, #11, 20), IAU / Minor Planet Center, via NASA/JPL
