Mars is accompanied by a pair of small moons — Phobos and Deimos — in addition to 4 Trojan asteroids that observe the Purple Planet in its journeys across the Solar.

Trojan asteroids observe planets, together with Mars, Earth, and Jupiter, positioned 60 levels forward of or behind their worlds. This angle supplies steady gravitational factors within the orbit for the asteroids as they transfer across the Solar. Every orbit of two huge objects produces 5 locations, often called Lagrange (or Lagrangian) factors, the place gravity of the 2 bigger objects balances, protecting smaller our bodies in a steady orbit round a central level.
