The Martian moons, Phobos and Deimos, may have been the result of a giant impact that sent rocks and debris into orbit around Mars, instead of asteroids that were captured by the planet’s gravity as previously thought. After going into orbit, the material from the giant impact aggregated and formed into small, low-mass moons.
