Apparent sizes of the moons of Mars, Deimos and Phobos, and the Moon as viewed from the surface of their respective planets (Mars' moons imaged by the Curiosity rover, 1 August 2013) Size comparison between Phobos, Deimos and the Moon (right) If viewed from Mars's surface near its equator, a full Phobos would look about one-third as big as a ...
Size comparison between Phobos, Deimos and the Moon (right) Deimos is a gray-colored body. Like most bodies of its size, Deimos is highly non-spherical with triaxial dimensions of 16.1 km × 11.8 km × 10.2 km (10.0 mi × 7.3 mi × 6.3 mi), corresponding to a mean diameter of 12.5 km (7.8 mi) which makes it about 57% the size of Phobos.

With an altitude of 5,989 km (3,721 mi), Phobos orbits Mars below the synchronous orbit radius, meaning that it moves around Mars faster than Mars itself rotates. [23] Therefore, from the point of view of an observer on the surface of Mars, it rises in the west, moves comparatively rapidly across the sky (in 4 h 15 min or less) and sets in the ...
"When I compare them to the moon like I did, you're able to actually see like, oh, Jupiter is about a 20th the size of the moon, Mars is about like 100th the size of the moon … you can kind of ...
Mars and the moon will be about four degrees apart on Wednesday evening. Christophe Lehenaff / Getty Images. From northern lights sightings to meteor showers and a supermoon, November has been an ...
Ganymede is the only Galilean moon of Jupiter named after a male figure—like Io, Europa, and Callisto, he was a lover of Zeus. In English, the Galilean satellites Io, Europa and Callisto have the Latin spellings of their names, but the Latin form of Ganymede is Ganymēdēs , which would be pronounced / ˌ ɡ æ n ɪ ˈ m iː d iː z / .

Since then, Mars has become slightly brighter, and on Friday, Aug. 19, it will be showcased next to the moon to create an eye-grabbing astron Moon and Mars to make celestial rendezvous in early ...
Earth vs Mars vs Moon gravity at elevation Radial gravity anomaly at the surface of the Moon in mGal. The acceleration due to gravity on the surface of the Moon is approximately 1.625 m/s 2, about 16.6% that on Earth's surface or 0.166 ɡ. [1]
