Mars has two known satellites, or moons, named Phobos and Deimos. These moons are small and irregularly shaped, resembling asteroids more than large, spherical moons like Earth’s.
Phobos, the larger of the two, orbits extremely close to Mars, completing an orbit in just about 7.6 hours. Deimos, smaller and farther out, takes approximately 30.3 hours to orbit the planet. Both moons are thought to be captured asteroids from the nearby asteroid belt, though some theories suggest they could have formed from debris after a collision involving Mars.
These moons are fascinating to scientists due to their composition and potential as sites for future exploration missions to aid in Mars studies.
