The Mars trojans are a group of objects that share the orbit of the planet Mars around the Sun. They can be found around the two Lagrangian points 60° ahead of and behind Mars. The origin of the Mars trojans is not well understood. One theory suggests that they were captured in its Lagrangian points as the Solar System was forming. However, spectral studies of the Mars trojans indicate this may not be the case. One explanation for this involves asteroids wandering into the Mars Lagrangian points later in the Solar System's formation. This is also questionable considering the very low mass of Mars.
Presently, this group contains seven asteroids confirmed to be stable Mars trojans by long-term numerical simulations but only three of them are accepted by the Minor Planet Center (†) and there is one candidate:
L4 (leading cloud):
L5 (trailing cloud):
- Trojan (astronomy)
- Minor planets that orbit near trojan points
