Identity crisis. Phobos and Deimos bear more resemblance to asteroids than to Earth’s moon. 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.
What is the smallest moon in the solar system?
The smallest moon is Deimos, at Mars, only seven miles in diameter, although its size now is rivaled by the small shepherd moons discovered by Cassini at Saturn and by others yet to be counted and named in the rings around Jupiter, Saturn and other giant gas planets in the outer Solar System.
What size is Deimos?
3,8525 мили
Is Deimos a dwarf planet?
Formation and composition. The dark moons are made up of material similar to Type I or II carbonaceous chondrites, the substance of asteroids and dwarf planets such as Ceres. They are tiny, with the smaller Deimos having a radius of only 3.9 miles (6.2 km). … The close orbit of Deimos is nearly circular.
Which is smaller than 7 moons in the solar system?
There are seven moons in our Solar System, including our own Moon, that are larger than Pluto. … Earth’s Moon, Jupiter’s moons Callisto, Io, and Europa, and Neptune’s moon Triton are all larger than Pluto, but smaller than Mercury.

Can you land on Phobos?
“The exact location of the landing on the surface of Phobos is a matter of chance. and we are using these analyses to prepare for the various possible scenarios,” Michael Wrasmann, from the DLR Institute of Space Systems, said in the same statement. The rover team’s touchdown prep also includes computer modeling.
Can we live on Deimos?
Mars, (or even teraforming the red planet) and Earth’s Moon, of course, are both viable options. So are Mars’ moons, Phobos and Deimos. These satellites are both small, rocky bodies. … But a tiny, habitable world is, after all, still habitable.
Why is Deimos not round?
Unlike Earth’s moon, which is round, Deimos is shaped like a lumpy potato. The moon does not have any atmosphere due to it being so little and no gravity too low maintain one. The surface of the moon is made up of regolith and solid rock.
