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

An international team led by researchers at Queen's University Belfast has identified Neptune's elusive Trojan asteroids, resolving a long-standing astronomical mystery. While telescope observations beginning in 1906 revealed "Trojan" and "Greek" populations leading and trailing Jupiter, similar families were later found orbiting Saturn and Uranus. Despite these discoveries, astronomers had not previously confirmed the existence of such asteroids around Neptune.
