Neptune's elusive Trojan asteroids found in Rubin Observatory data
Queen's University Belfast-led team doubles known trailing Trojans on long-lived orbits using early survey observations
An international team led by researchers at Queen's University Belfast has identified two asteroids and a third candidate as permanent members of Neptune's trailing Trojan population, resolving a mystery that has eluded astronomers for decades. Schwamb said the team had been able to double the number of known objects in this population on long-lived orbits.
