Mars has two small, funky-looking moons with strange orbits, and they may suggest that the red planet once had rings, like some of the larger planets in our solar system. The two lumpy moons ...

It's possible that Mars' moons were originally asteroids that were captured by the planet's gravitational pull. There's also a theory that the two moons were created after a large object collided with ...

Mars' two moons, Phobos and Deimos, are small, irregular, but orbit in the same equatorial plane as the red planet. Although they've long been thought to be captured asteroids, those orbits would ...

The two small moons of Mars, Phobos (about 22km in diameter) and Deimos (about 13km in diameter), have been puzzling scientists for decades, with their origin remaining a matter of debate.

The origins of Mars's moons have long puzzled scientists. Two main hypotheses have been proposed: that Phobos and Deimos are captured asteroids or that they formed from debris created by a massive ...

MANY MOONS AGO Mars’ moons, Deimos (left) and Phobos (right), might have formed out of rocks blasted off the Red Planet by a large asteroid, a new study suggests.

Mars, the fourth planet from the Sun, is a subject of fascination for astronomers. Though significantly smaller than Earth, this red-hued world has two moons that continue to spark debate among ...

Of the two moons, Phobos is larger and closer to Mars; it is 17 miles across and orbits the Red Planet three times a day. Deimos is 9 miles across and takes 30 hours to make a revolution.

Japan is ready to mine Mars’ largest moon after successfully completing all of the compulsory “space contamination” paperwork. Japanese space agency JAXA hopes to travel to the Ma… ...
