A transit of Phobos from Mars usually lasts only thirty seconds or so, due to the moon's very rapid orbital period of approximately 7.6 hours. Because Phobos orbits close to Mars and in line with its equator, transits of Phobos occur somewhere on Mars on most days of the Martian year. Its orbital inclination is 1.08°, so the latitude of its ...
A transit of Deimos across the Sun as seen from Mars occurs when Deimos passes directly between the Sun and a point on the surface of Mars, obscuring a small part of the Sun's disc for an observer on Mars. During a transit, Deimos can be seen from Mars as a small dark spot rapidly moving across the Sun's face. [1] [2]
Phobos (/ ˈ f oʊ b ə s /; systematic designation: Mars I) is the innermost and larger of the two natural satellites of Mars, the other being Deimos. The two moons were discovered in 1877 by American astronomer Asaph Hall. Phobos is named after the Greek god of fear and panic, who is the son of Ares (Mars) and twin brother of Deimos.
Meanwhile, most of the rest of the US will be able to witness the eclipse in at least some way. Monday’s eclipse will last for four minutes and 28 seconds, twice as long as the last solar ...

The Phobos 2 infrared spectrometer (ISM) obtained 45000 spectra in the near infrared (from 0.75 to 3.2 μm) in the equatorial areas of Mars, with a spatial resolution ranging from 7 to 25 km, and 400 spectra of Phobos at 700 m resolution. These observations made it possible to generate the first mineralogical maps of the planet and its ...
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.
Note the many solar prominences ejecting from the sun. From 1900 to 2100, the state of New Hampshire will have recorded a total of 78 solar eclipses, two of which are annular eclipses and four of which are total eclipses. One of the annular solar eclipses occurred on May 10, 1994, and the other will occur on July 23, 2093.
