Martian moon Deimos seen crossing the face of Mars in this sequence of Thermal Infrared Imager images acquired during the Hera mission's gravity-assist flyby of Mars on March 12, 2025.

Deimos is tidally locked to Mars, meaning that like Earth's moon, it continually shows the same face to the Red Planet. Most previous images of the small, 7.7-mile-wide (12.4 kilometers ...

On a flyby of Mars, the European Space Agency (ESA) captured a rare photo of its second moon - but what do we know about it? It's called Deimos, and is much smaller and more mysterious than Phobos ...

capturing unprecedented images of Mars' lesser-known moon, Deimos. Mars has two moons, Phobos and Deimos, but scientists know relatively little about them, especially the smaller one, Deimos.

capturing the less-visible side of the tidally-locked moon. Deimos measures just over 7 miles across. Scientists believe Deimos could be a leftover chunk from Mars or a gravitationally captured ...

Hera used its trio of instruments to hone in on Mars and one of its small moons – the first object photographed by its cameras beyond Earth. The ESA said Hera took the photographs of Deimos from just ...

Deimos is about 15,000 miles from Mars. Scientists have previously speculated that it may actually be a piece of asteroid, not a moon. Hera got as close as 1,000 kilometers, or about 620 miles ...

A space exploration mission to study an asteroid that NASA deliberately crashed a spacecraft into three years ago has taken stunning bonus images of Mars and its moon Deimos en route to its final ...

The Martian moons of Deimos and Phobos still puzzle planetary scientists. But they are now sure that they aren’t gravitationally captured asteroids.
