Maria Camarca (b. 1996) is an American observational planetary scientist at the California Institute of Technology. She uses ALMA and JWST to understand the regolith generation and evolution on Solar System bodies like Callisto, including its history of bombardment and infall by (micro)meteorites, and Keck to study the composition of comets.Naming citation (WGSBN Bull. 6, #10, 9), IAU / Minor Planet Center, via NASA/JPL
