 Context examples 


Mars has two small moons, Phobos and Deimos.

(Solar Eruptions Could Electrify Martian Moons, NASA)

The crash also created a ring of rocky debris around Mars that may have later clumped together to form its moons, Phobos and Deimos.

(Ancient Asteroid Impact Explains Martian Geological Mysteries, The Titi Tudorancea Bulletin)

In fact, Phobos, one of Mars’ two moons (Deimos is the other), is getting closer to the Red Planet, and researchers think that in about 70 million years, it will break apart, potentially creating more rings.

(Mars May Have Had Rings, and May Once Again, VOA News)

Although this study focused on Phobos, similar conditions are expected at Deimos, since both moons have no atmosphere and are directly exposed to the solar wind – a stream of electrically conducting gas, called a plasma, that’s constantly blowing off the surface of the Sun into space at around a million miles per hour.

(Solar Eruptions Could Electrify Martian Moons, NASA)

Such an impact would also be expected to have generated a ring of material around Mars that later coalesced into Phobos and Deimos; this explains in part why those moons are made of a mix of native and non-Martian material.
