Abstract | Objects orbiting in the Lagrangian L4 and L5 points – called Trojan objects – lie 60° ahead of and behind a given planet in its orbit. In particular, these objects are of great interest because they can be dynamically stable over billions of years, implying that they carry precious information about the early solar system. The total population of large Neptunian Trojans (diameter > 50km) has been estimated to be at least the same as that of Jupiter Trojans of equivalent size. A total of six Neptune Trojans have been found to date, and they appear to be primordial objects stable over 4Gyr. Surprisingly, two of these objects possess high inclinations within the 25–30° range, thus challenging models of Trojan formation. |
