Neptune Has a Trojan
Written by Fraser Cain
Astronomers have discovered a new object which shares a very similar orbit with Neptune. Part of a classification of objects called Trojans, 2001 QR322 is 230 km across and requires 166 years to orbit the Sun. Although clusters of Trojans have been found following Jupiter's orbit, none have ever been found to share an orbit with any other giant planet; although, they've been predicted for years.
