Mars has how many satilites
Answers
Mars has 2 satellites.
Answer:
Mars has two small satellites, Phobos and Deimos (fear and terror), which were discovered by the American astronomer Asaph Hall in 1877. They were named after the attendants of Mars in Greek mythology.
⠀⠀⠀⠀Both satellites are heavily cratered, which indicates that their surfaces are at least 3 billion years old (Fig. 2). But only Deimos appears to be covered with a fine dust, which gives its surface a smoother appearance. This dust may exist because the surface is more easily pulverized by impacts, or it may be the result of a large impact the shaped the moon's southern hemisphere. The surface of Phobos is extensively scored by linear grooves that are deepest near the huge impact crater Stickney (named after the Asaph Hall's wife, Angeline Stickney Hall, who collaborated with him in many of his astronomical observations) but that define planes cutting through the satellite and parallel to its intermediate axis that points along its direction of orbital motion. The grooves are probably fractures, enhanced by the collision that produced Stickney. There is some evidence that tidal action is bringing Phobos, which is already inside Roche's limit, closer to Mars. The satellite will either disintegrate (perhaps to form a ring) or crash into Mars in about 100 million years.
