AI overview
A planetesimal is a small, rocky object in space that forms in the early stages of planetary development, combining together to eventually create planets. They matter because studying them—like the pristine planetesimal 486958 Arrokoth visited by spacecraft—helps scientists understand how planets form and what the early solar system was like.
