Solar eclipses on Mars

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.[1][2] Neither moon's apparent diameter is large enough to cover the disk of the Sun, and therefore they are annular solar eclipses and can also be considered transits.
