Deimos in fiction
*In part 3 chapter 3 (the "Voyage to Laputa") of Jonathan Swift's famous satire Gulliver's Travels, a fictional work written in 1726, the astronomers of Laputa are described as having discovered two satellites of Mars.

(d´ms), in astronomy, one of the two moons, or natural satellites, of Mars.
Deimos is the outer of the two satellites of Mars. Both these moons were discovered by the American astronomer Asaph Hall in 1877. A small, irregular, cratered body approximately 15x12x11 km (9x7x7 miles) across, Deimos circles the planet every 30.

Mars II
Deimos [DEE-mos] (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 surface materials.
Deimos is farther away and moves slowly from east to west. Deimos would look like a small dot of light in the sky. Phobos is slowly moving closer to Mars. In another 50 to 100 million years, it will crash into Mars.

This computer mosaic of was made with images acquired from Viking Orbiter during one of its close approaches to the moon. The 15-km (9-mi) diameter Deimos circles every 30 hours.

If all of the planets are named after Roman gods, why is it that the moons of Mars (the Roman god of war) are Deimos and Phobos when those are the sons of the Greek god of war Ares?
The Answer ...
Deimos
The outer satellite of Mars, 12 × 13 km, P = 1.26 days; e = 0.003; inclination of orbit to planetary equator 1°.6. Visual geometric albedo 0.06. Mariner 9 has shown that both Phobos and Deimos are locked in synchronous rotation with Mars.

These are examples of what are called minor satellites: small chunks of rock in orbit around planets as compared with large satellites like the Earth's Moon. As the adjacent images show, they are very irregular in shape.
Deimos and Phobos
These two odd shaped worlds are the moons of the planet Mars. They are extremely small only 12.6 and 22.2 kilometers respectively. That is smaller than most towns. Their small size causes their gravity to be very weak.
DEIMOS
Deimos (meaning "terror") is the smaller of the two tiny moons of Mars. Deimos is only 7.8 miles (12.6 km) across and has a mass of 1.80 x 1015. It orbits at a mean distance of 14,300 miles (23,000 km) from Mars. It was discovered by in 1877.
Deimos
Description
When most people think of a moon, they think of the relatively large whitish globe that they see at night and sometimes during the day. While this is a moon, it is not typical of moons in the solar system.
Deimos, like , it is oblong in shape and heavily scarred with craters. It was first photographed by Mariner 9 in 1971.

Deimos, the outer moon, is 12 by 16 km (7.5 by 10 miles) but is farther away from Mars at about 23,000 km (14,300 miles), and so circles the planet every 30 hours.
Deimos' orbital period around Mars is longer than Phobos' as it is further out. It takes Deimos 30 hours and 18 minutes to orbit the planet once.
Phobos and Deimos move in circular, equatorial orbits, and they rotate synchronously (that is, they keep the same face permanently turned toward the planet). All these characteristics are direct consequences of the tidal influence of Mars.

Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Martian Trojan asteroid. Mars can be seen from Earth with the naked eye. Its apparent magnitude reaches âˆ'2.
In contrast, the surface of Deimos appears smooth, as its many craters are almost completely buried by large quantities of fine debris.
Phobos orbits at a distance of less than 6000 km from the surface of Mars and, with a maximum diameter of 27 km, is larger than Deimos.
In Greek mythology, Mars had two evil twin sons: Phobos (fear) and Deimos (terror). These are mentioned in the Iliad.
Mars has two moons, Phobos and Deimos. They are both very small, both being less than 30 km across. It is likely that they were both asteroids that have been captured by Mars.
Comerford's team found 32 black hole pairs out of 2,000 within the 50,000-strong Deep Imaging Multi-Object Spectrograph (DEIMOS) survey conducted with the ten-metre Keck II telescope on Mauna Kea in Hawaii.
Mars has two small, heavily cratered moons, Phobos and Deimos, which some astronomers consider asteroidlike objects captured by the planet very early in its history. Phobos is about 21 km (about 13 mi) across; Deimos, only about 12 km (about 7.5 mi).
[21] (a) The outer moon of Mars, Deimos, orbits the planet at about 23,500 kilometers with a period of 1.26244 days. Our own Moon, at about 385,000 kilometers, takes 27.32 days to orbit Earth.
As you can see, the too moons, Phobos and Deimos, are quite irregular in shape - sort of potato shaped and small. They also appear to have very low densities (mainly rocky), like the objects seen in the asteroid belt.

mission to Mars, launched in 1971, achieved global imaging of the surface, including the first detailed views of the Martian volcanoes, Valles Marineris, the polar caps, and the satellites Phobos and Deimos.
Jonathan Swift described the two moons of Mars even though they were not discovered until over 150 years later. For the record he described Phobos' orbital period as 10 hours (very close to the real figure of 7.6) and Deimos' as 21.
Mars is the fourth planet from the Sun with an average distance to the Sun of 2.28 × 108 km or 1.52 AU. It is a superior planet in that its orbit is larger than the Earths. It has two satellites, Phobos and Deimos.
