During a transit, Phobos can be seen from Mars as a large black disc rapidly moving across the face of the Sun. At the same time, the shadow ( antumbra ) of Phobos moves across the Martian surface. The event could also be regarded as a particularly quick and shallow annular solar eclipse by Phobos.
Annular eclipse of the Sun by Phobos (Curiosity, 20 August 2013) Eclipse of the Sun by Phobos, the larger of the two moons of Mars, in real time (Curiosity, 20 August 2013) The two moons of Mars, Phobos and Deimos, are much smaller than Earth's Moon, greatly reducing the frequency of solar eclipses on that planet.
The Sun's angular diameter as seen from Mars, by contrast, is about 21'. Thus there are no total solar eclipses on Mars as the moons are far too small to completely cover the Sun. On the other hand, total lunar eclipses of Phobos happen almost every night. [26] The motions of Phobos and Deimos would appear very different from that of Earth's Moon.
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.
More people currently live in the path of totality compared to the last eclipse . An estimated 31.6 million people live in the path of totality for 2024’s solar eclipse, compared to 12 million ...
Deimos transits the Sun, as viewed by the Mars Opportunity rover on 4 March 2004. Deimos transit on 20 January 2024, as captured by the Mars rover Perseverance on sol 1037 of its mission. 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 ...
The maximum brightness of Phobos at "full moon" is about magnitude −9 or −10, while for Deimos it is about −5. [9] By comparison, the full Moon as seen from Earth is considerably brighter at magnitude −12.7. Phobos is still bright enough to cast shadows; Deimos is only slightly brighter than Venus is from Earth. Just like Earth's Moon ...
During the August 2017 total solar eclipse, the then-president went viral when he ignored all eclipse safety recommendations by gazing directly at the sun with his naked eyes
