WebInclination – 0.93° Orbital Period – 30.312 hours Dimensions – 15 km × 12.2 km × 11 km Radius – 6.2 km Mass – 1.4762×1015 kg Volume – 998 km3 Rotation – Synchronous Temperature – ≈ 233 K (-40°F) Apparent Magnitude – 12.89 The moon Deimos is designated Mars II. It is one of the two natural satellites of Mars, the other one being Phobos. WebContext. Study the rotation of a celestial body is an efficient way to infer its interior structure, and then may give information of its origin and evolution. In this study, based on the latest shape model of Phobos from Mars Express (MEX) mission, the polyhedron approximation approach was used to simulate the gravity field of Phobos. Then, the gravity information …

WebJan 1, 1999 · Their orbital eccentricity and inclination can be enhanced greatly by the orbital resonance. Particles from Phobos would form a thin dust ring where dust radius is dominant in 20-20Cpm. On the other hand, particles from Deimos would form an extended dust torus. Collisions of ring particles on Phobos and Deimos may be the most important dust source. Phobos has dimensions of 27 km × 22 km × 18 km, and retains too little mass to be rounded under its own gravity. Phobos does not have an atmosphere due to its low mass and low gravity. It is one of the least reflective bodies in the Solar System, with an albedo of about 0.071. Infrared spectra show that it has … See more Phobos is the innermost and larger of the two natural satellites of Mars, the other being Deimos. The two moons were discovered in 1877 by American astronomer Asaph Hall. It is named after Phobos, … See more The origin of the Martian moons is still controversial. Phobos and Deimos both have much in common with carbonaceous C-type asteroids, … See more Phobos is synchronously orbiting Mars, where the same face stays facing the planet at 6,000 km (3,700 mi) above the Martian surface. A space elevator could extend down from Phobos to Mars 6,000 km, about 28 kilometers from the surface, and just out of the … See more Phobos was discovered by astronomer Asaph Hall on 18 August 1877 at the United States Naval Observatory in Washington, D.C., … See more The orbital motion of Phobos has been intensively studied, making it "the best studied natural satellite in the Solar System" in terms of … See more Launched missions Phobos has been photographed in close-up by several spacecraft whose primary mission has been to photograph Mars. The first was Mariner 7 in 1969, followed by Mariner 9 in 1971, Viking 1 in 1977, Phobos 2 in … See more • List of natural satellites • List of missions to the moons of Mars • Phobos and Deimos in fiction See more in b.c
