Mars/Moons
He discovered Deimos the next night, and Phobos six nights after that. Ninety-four years later, NASA’s Mariner 9 spacecraft got a much better look at the two moons from its orbit around Mars.
What planet has Phobos as its moon?
Mars
Phobos (/ˈfoʊbɒs/; systematic designation: Mars I) is the innermost and larger of the two natural satellites of Mars, the other being Deimos. Both moons were discovered in 1877 by American astronomer Asaph Hall.
Why does Mars have two moons?
The inner part of the ring formed a large moon. Gravitational interactions between this moon and the outer ring formed Phobos and Deimos. Later, the large moon crashed into Mars, but the two small moons remained in orbit. This theory agrees with the fine-grained surface of the moons and their high porosity.
Can you see Phobos and Deimos from Mars?
Even from Mars, the moons don’t look like moons. The more distant moon, Deimos, appears more like a star in the night sky. Phobos orbits only 3,700 miles (6,000 km) from the Martian ground. Its surface is marred by debris that may have come from impacts on Mars.
Can you see Phobos and Deimos from Mars surface?
Interestingly, because of the two moons’ extreme closeness to their host planet, there are actually parts of Mars from which Phobos and/or Deimos would not be visible — the bulge of Mars’ own curvature gets in the way!

Does Mars have a moon?
Yes, Mars has two small moons named Phobos and Deimos. Their names mean fear and panic in Latin. Phobos and Deimos are not round like our Moon.
How did the moons Phobos and Deimos get their names?
Both were discovered by Asaph Hall in August 1877 and are named after the Greek mythological twin characters Phobos (panic/fear) and Deimos (terror/dread) who accompanied their father Ares into battle. Ares, god of war, was known to the Romans as Mars. Compared to the Earth’s Moon, the moons Phobos and Deimos are small.
What is the name of the two moons of Mars?
Phobos and Deimos. (moons of Mars) Mars has two small moons: Phobos and Deimos. Phobos (fear) and Deimos (panic) were named after the horses that pulled the chariot of the Greek war god Ares, the counterpart to the Roman war god Mars. Both Phobos and Deimos were discovered in 1877 by American astronomer Asaph Hall.
What is the relationship between the moons of Mars and Phobos?
Both moons are tidally locked, always presenting the same face towards Mars. Since Phobos orbits Mars faster than the planet itself rotates, tidal forces are slowly but steadily decreasing its orbital radius.
What are the two smallest moons in the Solar System?
Both are tiny — the larger, Phobos, is only 14 miles across (22 kilometers), while the smaller, Deimos, is only 8 miles (13 km), making them some of the smallest moons in the solar system.
