NASA's Mars Reconnaissance Orbiter took this image of Phobos, the larger of Mars' two moons. This Martian moon orbits the closest to its primary of all the known moons in the solar system--a mere few thousand miles above the surface of Mars. Credit: NASA / JPL / University of Arizona


Stickney Crater Image Credit: HiRISE, MRO, LPL (U. Arizona), NASA Stickney Crater, the largest crater on the martian moon Phobos, is named for Chloe Angeline Stickney Hall, mathematician and wife of astronomer Asaph Hall. Asaph Hall discovered both the Red Planet's moons in 1877. Over 9 kilometers across, Stickney is nearly half the diameter of Phobos itself, so large that the impact that blasted out the crater likely came close to shattering the tiny moon.


#OnThisDay in 1877 American astronomer Asaph Hall discovers the Mars moon Deimos.


This is Mars' moon Deimos. It is one of two moons on the planet Mars: Deimos and Phobos. Deimos is the small of the two Martian moons and has an odd shape. This moon has a more even, smoother surface, due to partial filling of some of its craters over time. More Mars planet facts for teachers and students at:


Space Facts - Mars has two small moons: Phobos and Deimos. Phobos (fear) and Deimos (panic) were named after the horses that pulled the chariot of the Greek war god Ares, the counterpart to the Roman war god Mars. Teachers and students, get more Mars Moon Facts at:
