How big are Phobos and Deimos compared to Mars?
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. Both are also made up of material that resembles Type I or II carbonaceous chondrites, the substance that makes up asteroids.
What is the size of Deimos?
6.2 km
Deimos/Radius
How big is Mars moon Phobos?

Phobos/Radius
How big is Deimos compared to Mars?
Deimos is the smaller of Mars’ two moons. Being only 9 by 7 by 6.8 miles in size (15 by 12 by 11 kilometers), Deimos whirls around Mars every 30 hours.
Is Deimos bigger or smaller than Phobos?
Overview. 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.
How much smaller is Phobos than the moon?
If viewed from Mars’s surface near its equator, full Phobos looks about one-third as big as a full moon on Earth.
Which is bigger Phobos or Deimos?
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.
How wide is Phobos?
22.533 km
Phobos/Diameter
Are Phobos and Deimos visible from Mars?
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!
Can you see Phobos and Deimos from Mars surface?
Surprisingly, despite its orbit being nearly in the plane of Mars’s equator and despite its very close distance to Mars, there are some occasions when Phobos escapes being eclipsed. Phobos and Deimos both have synchronous rotation, which means that they have a “far side” that observers on the surface of Mars can’t see.
How are Phobos and Deimos related to Mars?
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.
How big is Deimos moon compared to Mars?
Some of the interesting facts about Deimos moon is given below: Deimos is an irregular satellite of Mars with a diameter of around 12 km. Despite the smaller size, it has a crater named Voltaire with an average diameter of around 3 km. As you read above the largest of Mars’s moon Phobos getting closer to Mars and could collide in the future.
Which is the larger moon Mars or Phobos?
Phobos – Has a radius of 11.1 kilometers and is the larger Martian satellite. It orbits closely around Mars and it moves even faster than Mars can rotate on its own axis. It rises in the west and after a little more than 4 hours it already sets on the east.
Why are there so many craters on Phobos and Deimos?
The Moon, Phobos, and Deimos all have lots of craters from asteroid impacts due to not having an atmosphere. Deimos has the least craters out of the 3 due to its smaller size. None of the moons have the capacity to support the existence of liquid water. But the Moon and Phobos do seem to have ice.
