Trojan points and satellites, Physics

Assignment Help:

Trojan points:

It is L4 & L5, the two dynamically stable Lagrange points (under certain conditions).

Trojan satellites:

This is the satellites that orbit a body at one or the other Trojan points relative to secondary body. There are many examples of this in our own solar system: daughter satellites which orbit into the Trojan points of the Saturn-Tethys system, a group of asteroids that orbit in the Trojan points of Jupiterand an extra satellite (Helene) which orbits in the forward Trojan point of Saturn and Dione.
