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.
Where are the satellites Phobos and Deimos located?
Mars
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.
Can you see Phobos and Deimos from Earth?
For any latitudes beyond 83 degrees north or south of the equator on the Mars, for example, Deimos can never be seen. Phobos, being the closer of the two moons moves in an even lower orbit and can never been seen from latitudes above 70 degrees north or south of the Martian equator.
How often do the paths of the martian moons Phobos and Deimos cross in front of the sun?
Twice every Martian year
Twice every Martian year, near the seasonal equinoxes, the paths of the Martian moons Phobos and Deimos cross in front of the Sun as seen by Curiosity. This animation shows the 22km diameter Phobos in transit across the sun on Sol 2359.
How far is Phobos and Deimos from Mars?

Can Mars be seen at night without a telescope?
Yes, as one of the five brightest planets, Mars is visible without a telescope. In many cases Mars will be a small reddish dot in the night sky. The best period to see Mars is when the Earth and Mars are closest. When the two planets are at their closest distance, this is known as opposition.
How were Phobos and Deimos formed?
The moons of Mars may have started with a huge collision with a protoplanet one third the mass of Mars that formed a ring around Mars. The inner part of the ring formed a large moon. Gravitational interactions between this moon and the outer ring formed Phobos and Deimos.
Why does Phobos rise in the west and set in the East?
Like our own Moon, both Deimos and Phobos move from west to east. Since the Earth rotates from west to east on its axis more than 27 times faster than it takes for the Moon to revolve once around the Earth, we’re accustomed to seeing it rise in the east, cross the sky and set in the west.
What is the distance between Mars and Deimos?
14,576 miles
Facts about Deimos: Semi-major axis around Mars (distance from planet’s center): 14,576 miles (23,458 km)
