Queen's University Belfast students find Neptune's elusive Trojan asteroids

An international team led by researchers at Queen's University Belfast has discovered Neptune's elusive Trojan asteroids, a finding that has eluded astronomers for decades. Since 1906, telescope observations identified populations of asteroids leading and trailing Jupiter, known as the "Trojan" and "Greek" populations, with similar families found orbiting Saturn and Uranus, but not Neptune. The Queen's-led team's discovery resolves the mystery of the missing Trojans.
