Deimos (/ ˈ d aɪ m ə s /; systematic designation: Mars II) [11] is the smaller and outer of the two natural satellites of Mars, the other being Phobos. Deimos has a mean radius of 6.2 km (3.9 mi) and takes 30.3 hours to orbit Mars. [5] Deimos is 23,460 km (14,580 mi) from Mars, much farther than Mars's other moon, Phobos. [12]
Swift is an impact crater on Mars's moon Deimos. It is about 3 km (1.9 mi) in diameter. [2] [3] Swift is named after Jonathan Swift, whose 1726 book Gulliver's Travels predicted the existence of two moons of Mars. [4] Swift is one of two named features on Deimos, the other being Voltaire.
The motions of Phobos and Deimos would appear very different from that of Earth's Moon. Speedy Phobos rises in the west, sets in the east, and rises again in just eleven hours, while Deimos, being only just outside synchronous orbit, rises as expected in the east but very slowly. Despite its 30-hour orbit, it takes 2.7 days to set in the west ...
Voltaire is an impact crater on Mars's moon Deimos and is approximately 3 km (1.9 mi) across. [2] [3] Voltaire crater is named after François-Marie Arouet, a French Enlightenment writer who was better known by the pen name Voltaire, who in his 1752 short story "Micromégas" predicted that Mars had two moons.
The habitability of natural satellites is the potential of moons to provide habitats for life, though it is not an indicator that they harbor it.Natural satellites are expected to outnumber planets by a large margin and the study of their habitability is therefore important to astrobiology and the search for extraterrestrial life.
Unlike Deimos, Phobos is heavily cratered, [30] with one of the craters near the equator having a central peak despite the moon's small size. [31] The most prominent of these is the crater Stickney , a large impact crater some 9 km (5.6 mi) in diameter, which takes up a substantial proportion of the moon's surface area.
A transit of Deimos from Mars lasts a maximum of about two minutes, due to its relatively rapid orbital period of about 30.3 hours.. Because they orbit Mars in low-inclination equatorial orbits, the shadows of Phobos or Deimos projected onto the surface of Mars exhibit a seasonal variation in latitude.
Aerial render of the Build The Earth project on a modified Airocean World Map. Build the Earth was created by YouTuber PippenFTS in March 2020 as a collaborative effort to recreate Earth in the video game Minecraft. [1] During the COVID-19 lockdowns, the server aimed to provide players with the opportunity to virtually experience and construct ...
