It's possible that Mars' moons were originally asteroids that were captured by the planet's gravitational pull. There's also ...

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 ...

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.

Mars’ moons could be the remains of an ill-starred asteroid that got too close to the Red Planet. A shredded asteroid origin could help explain mysterious features of the small, odd-shaped moons ...

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.

Phobos and Deimos, they say, were originally a binary comet that separated into two moons after it was captured by Mars’ gravitational field. First some background. Astronomers have two competing ...

Where did the moons of Mars come from? That’s a question scientists still can’t answer. We know that Earth’s moon was likely formed from a giant impact on our planet about 4.5 billion years ago.

The moons of Mars are not easy to explain. Both are small — Phobos is 16 miles (26km) across at its widest point, whereas, Deimos is just 10 miles (16km) — and lumpy.

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

Phobos is the largest of Mars’ two moons, the other one being Deimos. Scientists are uncertain about their history. They could be a pair of captured main-belt asteroids, two lobes of what once was a ...
