section_name: Trojans
paragraph_text: Trojans
  
  Trojans are populations that share an orbit with a larger planet or moon, but do not collide with it because they orbit in one of the two Lagrangian points of stability, L and L, which lie 60° ahead of and behind the larger body.
  
  In the Solar System, most known trojans share the orbit of Jupiter. They are divided into the Greek camp at L (ahead of Jupiter) and the Trojan camp at L (trailing Jupiter). More than a million Jupiter trojans larger than one kilometer are thought to exist, of which more than 7,000 are currently catalogued. In other planetary orbits only nine Mars trojans, 28 Neptune trojans, two Uranus trojans, and two Earth trojans, have been found to date. A temporary Venus trojan is also known. Numerical orbital dynamics stability simulations indicate that Saturn and Uranus probably do not have any primordial trojans.
