Unlike the Earth, in the eclipse on Mars, sunlight is not completely obscured, but a spot of shadow appears in the sun’s disk due to the small size of the moons that orbit the red planet, as shown in the video clip.
Two moons, Phobos and Deimos, revolve around Mars, and they each need about seven hours and 30 hours, respectively, to complete a full revolution around the planet, compared to the Earth’s moon, which needs about 27 days to complete its cycle.
Compared to the moon, which has a radius of about 1,737 km, the two moons of Mars are very small, with a radius of Phobos about 11 km and a radius of Deimos 6 km.
According to the Mashable website, solar eclipses on Mars occur more frequently and multiple times compared to Earth as a result of the speed of the two moons’ rotation around Mars.
