March 5, 2024: NASA released images of transits of the moon Deimos, the moon Phobos and the planet Mercury as viewed by the Perseverance rover on the planet Mars. Transits viewed from Mars by the Perseverance rover
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]
The Phobos monolith (right of center, casting long shadow) as taken by the Mars Global Surveyor (MOC Image 55103, 1998). The location of the monolith (HiRISE image PIA10368) The Phobos monolith is a large rock on the surface of Mars' moon Phobos. [1] It is a boulder, about 85 m (279 ft) across and 90 m (300 ft) tall.
Astronomers suspect Phobos and Deimos may be asteroids captured in orbit by Mars’ gravity or fragments scattered during a giant impact with Mars, but mysteries persist about the Martian moons.
Phobos is named after the Greek god of fear and panic, who is the son of Ares (Mars) and twin brother of Deimos. Phobos is a small, irregularly shaped object with a mean radius of 11 km (7 mi). It orbits 6,000 km (3,700 mi) from the Martian surface, closer to its primary body than any other known natural satellite to a planet.
Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. This picture is a true-colour image of Mars, taken from a distance of about 240,000 kilometres (150,000 mi) by the OSIRIS instrument on ESA's Rosetta spacecraft, during its February 2007 flyby of the planet. The image was generated using OSIRIS's orange (red), green ...
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. At any given geographical location on the ...
