Martian Solar Eclipse

Phobos might as well be walkin' on the Sun
Who knew solar eclipses on Mars were such a common event?

Solar eclipses on Mars are so common that one of its moons, Phobos, scoots across the disk of Sun on a near-daily basis. 

Why? Because Phobos is only 3,600 miles away from Mars. In comparison, our Moon is 249,000 miles away from Earth.

Mars rover Curiosity caught Phobos in transit across the Sun on September 13 (pictured to the right). 

A ho-hum sight for all of those caverns and channels on Mars, but not for first-time visitor Curiosity

Here's hoping there are many more eclipses for the rover to see.
