Summary

Recent spacecraft flybys have shown that at least one asteroid has a smaller companion. Ground-based telescopes, the Hubble Space Telescope, radar measurements, and brightness variations are also providing increasing evidence for binaries in our solar system. In his Perspective, Burns explains how these binaries may have formed and discusses the insights into collisions in our solar system gained from their study.
