However, the Martian moons orbit much closer to their planet than the distance between #Earth and Earth's moon. #Deimos, at far left, and #Phobos, beside it, are shown together as they actually were photographed by the Mast Camera (Mastcam) of the Mars rover #Curiosity on August 1, 2013.

This illustration provides a comparison for how big the moons of #Mars appear to be, as seen from the surface of Mars, in relation to the size that #Earth's moon appears to be when seen from the surface of Earth. Earth's moon actually has a diameter more than 100 times greater than the larger Martian moon, #Phobos.

New modeling indicates that the grooves on #Mars’ moon #Phobos could be produced by tidal forces—the mutual gravitational pull of the planet and the moon. Initially, scientists had thought the grooves were created by the massive impact that made #Stickney crater (lower right).

Image of #Phobos from the #Mars #ReconnaissanceOrbiter with #Stickney crater on the right. Phobos is the larger of Mars' two moons and is 17 x 14 x 11 miles (27 by 22 by 18 kilometers) in diameter. It orbits Mars three times a day, and is so close to the planet's surface that in some locations on Mars it cannot always be seen.
