Tucked at the edge of Earth's gravitational reach, a small celestial body once dismissed as a captured wanderer may in fact be a piece of our own Moon — a fragment cast adrift by some ancient, violent collision billions of years ago. Researchers have found chemical signatures in this so-called second moon that align far more closely with lunar material than with typical asteroid composition, quietly challenging the assumptions astronomers have long held about what orbits our world and why. The discovery, still unfolding, invites us to reconsider not only the Moon's turbulent past but the hidde
