Arecibo radar image of Dione Regio on Venus. White arrows indicate radar-bright features that potentially represent debris from previous volcanic eruptions (Campbell et al. 2017). (Right) Goldstone Solar System Radar image of the near-Earth asteroid (NEA) 2017 BQ 6 showing sharp facets on this object. NEAs display a range of surface features, from which evolution and collisional processes can be constrained, and are important to characterize for planetary defense.
