The inner part of the ring formed a large moon. Gravitational interactions between this moon and the outer ring formed Phobos and Deimos. Later, the large moon crashed into Mars, but the two small moons remained in orbit. This theory agrees with the fine-grained surface of the moons and their high porosity.

Phobos is a small, irregularly shaped object with a mean radius of 11 km (7 mi). It orbits 6,000 km (3,700 mi) from the Martian surface, closer to its primary body than any other known natural satellite to a planet. It orbits Mars much faster than Mars rotates and completes an orbit in just 7 hours and 39 minutes.
Mars’s moons don’t get much credit. But they’re small, lifeless, and weird little things. Here’s everything you should know about them.
Deimos (moon) Deimos / ˈdaɪməs / (systematic designation: Mars II) [11] is the smaller and outer of the two natural satellites of Mars, the other being Phobos. Deimos has a mean radius of 6.2 km (3.9 mi) and takes 30.3 hours to orbit Mars. [5] Deimos is 23,460 km (14,580 mi) from Mars, much farther than Mars's other moon, Phobos. [12]
Among them is Ganymede, the largest and most massive moon in the Solar System. Its 87 known irregular moons are organized into two categories: prograde and retrograde. The prograde satellites consist of the Himalia group and three others in groups of one. The retrograde moons are grouped into the Carme, Ananke and Pasiphae groups.
Stickney (crater) Heavily saturated false color image of Stickney with the smaller crater Limtoc within it, as seen by MRO on 23 March 2008. Stickney is the largest crater on Phobos, which is a satellite of Mars. It is 9 km (5.6 mi) in diameter, taking up a substantial proportion of the moon's surface.
The location of the monolith (HiRISE image PIA10368) The Phobos monolith is a large rock on the surface of Mars ' moon Phobos. [1] It is a boulder, about 85 m (279 ft) across and 90 m (300 ft) tall. [2][3] A monolith is a geological feature consisting of a single massive piece of rock. Monoliths also occur naturally on Earth, but it has been ...
