NASA Rover Captures What A Solar Eclipse Looks Like On Mars

In our Solar System, any planet with moons has a chance for a solar eclipse.
Solar eclipses are possible on Earth, and occur whenever the Moon aligns with the Earth-Sun plane... [+] during a new Moon. This same principle applies to any planet with a moon.

They occur whenever a moon passes directly between its planet parent and the Sun.
An illustration of the Sun-Moon-Earth configuration setting up a total solar eclipse. When the... [+] Moon's shadow falls on Earth when the nearer-to-the-Sun node aligns, we get a solar eclipse: total if the Moon's shadow falls on the Earth, annular if the shadow ends before reaching Earth, and partial if the alignment is too imperfect.

From planet Earth, they can appear partial, total, or annular.
From Earth, eclipses can be partial, annular, or total, owing to the large angular size of our Moon... [+] as seen from Earth's surface. From Mars, both of its moons are too small to create total solar eclipses.

But on Mars, only partial or annular eclipses occur.
The closer and larger of Mars's moons, Phobos, makes for a completely alien sight during solar... [+] eclipses. Annual eclipses occur frequently on Mars, even appearing perfectly aligned on occasion to the Curiosity Rover.
