The larger moon, Phobos, tops out at about 17 miles across at its widest point, and Deimos is only about half that size. ... unless Mars and Deimos built themselves from the same material.

Deimos, the smaller of the two moons of Mars, might be a chip off the old block — quite literally. ... How the moon would have formed from Mars, however, is not yet clear.

During a flyby of Mars on Wednesday (March 12), ESA's Hera spacecraft inaugurated use of its science instruments to image the smaller of the planet's two moons, Deimos.

The moon has a mean radius of about 6.2 kilometers (3.85 miles) and goes around Mars every 30.3 hours or so. This truly stunning image is just the cherry on top of the observations.
