Deimos

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.

Deimos and Phobos are composed of carbon-rich rock like C-type asteroids and ice. Both are heavily cratered. Deimos and Phobos are probably asteroids perturbed by Jupiter into orbits that allowed them to be captured by Mars. More about Deimos ...

Deimos Related Category: Astronomy: General (d´ms), in astronomy, one of the two moons, or natural satellites, of Mars.

Deimos 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.

Mosaic of Deimos 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.

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 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.

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 1.80x1015. It orbits at a mean distance of 14,300 miles (23,000 km) from Mars.

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 in astronomy, one of the two moons, or natural satellites, of Mars. Desdemona in astronomy, one of the natural satellites, or moons, of Uranus. Despina in astronomy, one of the natural satellites, or moons, of Neptune.

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.

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.

Though Deimos does revolve slower than Mars rotates, its speed is so comparable it that stays in the Martian sky for more than two and a half Earth days from moonrise to moonset.

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.

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.

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.

Phobos and Deimos of Mars look like this. Another good sign that a moon may be captured is if it orbits in a direction opposite to that of the mother planet. An example of a moon of this kind is Neptune's moon Triton.

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 (the sons of the Greek God of war)? Is the 'face on Mars' really only just a hill?

HALL, ASAPH Asaph Hall (1829-1907) was an American astronomer who discovered Mars' two moons, Phobos and Deimos, on August 12, 1877, at the U. S. Naval Observatory's 26-inch refracting telescope.
