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 ...

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, ...

How Mars got its two moons, Phobos and Deimos, is a bit of a mystery. They are small, 27 and 15 kilometres across respectively, and both orbit around the planet’s equator.

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.

How "asteroid detectives" protect Earth from potential impacts 03:15. A space probe flying past Mars captured images of the red planet's small, mysterious moon.

The origins of Mars’s moons Phobos and Deimos have long been an enigma, but they may have been formed when a icy, comet-like object slammed into the Red Planet. By Leah Crane.

The moons’ small size and quirky dimensions led to suggestions that they may be asteroids captured by Mars long ago. Not so, say researchers analyzing data recorded by Hope, which entered orbit ...

Mars, by comparison, has only two moons, Deimos and Phobos. ESA followed up the Jupiter video with a shorter sequence captured in March showing the larger moon Phobos passing in front of Deimos .

A new study has revealed that the weird parallel grooves on the surface of Mars' largest moon Phobos could be a sign that the Red Planet's gravity is ripping the satellite apart.

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. Some have ...

The UAE Space Agency’s Emirates Mars Mission (EMM) has released a number of stunning images taken of Mars’ moon Deimos in a campaign of close flybys.
