WebDec 19, 2024 · Phobos is a bit larger than Deimos, and orbits only 3,700 miles (6,000 kilometers) above the Martian surface. No known moon orbits closer to its planet. It whips around Mars three times a day, while the more distant Deimos takes 30 hours for each orbit. WebNov 1, 2014 · Phobos is in synchronous spin-orbit resonance around Mars, with identical rotational and orbital periods of 7.65 h.The analysis in our paper is based on the current Phobos rotation parameters (Table 1) recommended by the IAU (International Astronomical Union), (Seidelmann et al., 2002, Archinal et al., 2011), which include a drift of the …

WebPhobos is roughly 22 km in diameter and orbits closer to Mars, with a semimajor axis of 9,377 km. Deimos is smaller—roughly 12 km in diameter—and orbits farther from Mars, with a semimajor axis of 23,460 km. The orbital periods of the two moons ar... WebFeb 1, 2024 · Orbital Characteristics. As seen from the surface of Mars, Deimos rises in the east, and sets in the west. However, since the moon’s Sun-synodic orbital period of 30.4 hours is slightly longer than a Martian day (“sol”), which is 24.7 hours long, 2.7 Martian days would elapse between each successive rising and setting of the moon for an ... fishtail cooking utensils
