What planet has twin moons?
Mars
The two moons of Mars are Phobos and Deimos. They are irregular in shape. Both were discovered by American astronomer Asaph Hall in August 1877 and are named after the Greek mythological twin characters Phobos (fear) and Deimos (terror and dread) who accompanied their father Ares into battle.
Are there 2 moons?
The earth has picked up a second moon. It’s not very big. In fact it’s almost impossible to see. Astronomer Kacper Wierzchos says it’s an asteroid that’s roughly 9 feet in diameter that got captured by the earth’s gravity about 3 years ago.

Mars/Moons
Mars’ moons are among the smallest in the solar system. Phobos is a bit larger than Deimos, and orbits only 3,700 miles (6,000 kilometers) above the Martian surface. No known moon orbits closer to its planet. It whips around Mars three times a day, while the more distant Deimos takes 30 hours for each orbit.
Will Deimos crash into Mars?
It is not destined to crash into Mars like Phobos. Rather, Deimos is slowly moving farther away from Mars. Just like Earth’s moon, it is believed that Deimos will eventually leave the orbit of its parent planet, never to be see again.
