Deimos (moon) - Wikipedia
Deimos is composed of rock rich in carbonaceous material, much like C-type asteroids and carbonaceous chondrite meteorites. [25] . It is cratered, but the surface is noticeably smoother than that of Phobos, caused by the partial filling of craters with regolith. [citation needed] .
Deimos - NASA Science
Deimos is a dark body that appears to be composed of C-type surface materials, similar to that of asteroids found in the outer asteroid belt. Deimos was discovered on Aug. 11, 1877 by Asaph Hall. Hall named Mars' moons for the mythological sons of Ares, the Greek counterpart of the Roman god, Mars.

The surface of Deimos is gray and very dark; its reflectance is only 7 percent—about half that of the Moon’s surface. This fact and the satellite’s low mean density (about 1.5 grams per cubic centimetre) indicate a carbonaceous composition and suggest that Deimos may be a captured asteroid-like object.

Aug 26, 2024 · Deimos surface is heavily cratered. The moon’s composition consists of rock and ice. Deimos has a low albedo, indicating a dark surface. Its surface temperature ranges from -153°C to 27°C. Deimos has a very low mass of about 1.47 x 10^15 kilograms. The moon’s weak gravitational pull prevents it from capturing a stable atmosphere.

Deimos (or Mars II) is the smaller moon of Mars. Its name comes from the Greek word for terror. Its orbital period is 30.3 hours, which is 1.263 days. Deimos is only 15 kilometers in diameter. It is covered with craters, as Earth's moon and other bodies without an atmosphere are.

Deimos (Latin for Panic) is a moon of Mars and was named after an attendant of the Roman war god Mars. Deimos is a dark body that appears to be composed of C-type (blackish carbonaceous chondrite) surface materials.
Unlike Earth’s Moon, they are small irregularly shaped objects with a mean radius of about 11 km for Phobos and 6 km for Deimos (about 56 per cent of the size of Phobos). Phobos is heavily cratered with the biggest crater, named Stickney, reaching 9 km in diameter. On the other hand, Deimos is cratered too, but the surface is noticeably smoother
