Confirmed Binary and Triple Near-Earth Asteroids
Introduction
Near-Earth asteroids (NEAs) are small rocky bodies whose orbits bring them close to Earth. Recent radar and optical observations have revealed that many of these objects exist not as solitary rocks but as binary or triple systems, where two or three bodies orbit one another. This article examines the confirmed cases of such systems, presenting only verified, peer-reviewed findings to provide an accurate, factual overview of their physical properties, orbital dynamics, and significance for planetary science.
