Surface Geology and Evolution of Asteroid Ryugu: Insights From Hayabusa2 Global Mapping

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.
Abstract Rubble‐pile asteroids, characterized by loose aggregates of debris held together by gravity, represent both a significant planetary hazard and a key to understanding planetesimal formation. Geologic mapping of these bodies provides essential insights into their origins, evolution, and surface processes.
