Edgar G. Rivera-Valentín (b. 1986) is a scientist at the Lunar and Planetary Institute. His research focuses on the interactions of processes, such as atmosphere-regolith interactions, impact cratering's interactions with a body's composition, and interactions between radar and the near-surface of asteroids and planetary surfaces.Naming citation (WGSBN Bull. 5, #14, 21), IAU / Minor Planet Center, via NASA/JPL
