Deimos

The information I have suggests that Deimos and Phobos look somewhat similar to Earth’s moon, though they are much smaller in size.

The spacecraft will spend three years around Mars conducting science operations to observe Phobos and Deimos.

Recently it captured high-resolution images of Deimos, the smaller of the two Martian moons.

It remains unclear which of these two formation routes holds true for Mars’s moons, Phobos and Deimos—but we may soon have an answer.

The red planet Mars, fourth from Earth's sun, has two little moons: Phobos and Deimos.
