The bodies, known as Trojan asteroids (although it is not clear that they are rocky, rather than icy), travel around the Sun at the same distance from the Sun as Neptune. They sit about 60° ahead of the planet on its circular orbit, settled into a gravitational sweet spot known as a Lagrangian point.
Every planet has these sweet spots; in Jupiter's case, there are more than 1,800 asteroids in them. Those asteroids in the sweet spot 60° ahead of the planet are named after Greek warriors from Homer's Iliad; those 60° behind after the Trojans.
Hoe worden deze sweet spots veroorzaakt?
