Deimos is the smaller and outer of the 2 pure satellites of Mars, the opposite being Phobos. Deimos, doubtless an asteroid captured by Mars’ gravity, is extremely non-spherical with a imply diameter of 12.5 km (about 57% the dimensions of Phobos) and it orbits 23,460 km from Mars (Deimos’ orbit is slowly getting bigger and it’s anticipated to ultimately escape Mars’ gravity). Escape velocity from the floor of Deimos is simply 5.6 m/s so a human can principally leap off of it.
Within the universe of The Expanse TV sequence (a political sci-fi drama set in mid-Twenty fourth century when people have colonized all the Photo voltaic system) Deimos hosts navy amenities and a deep radar station for Martian Congressional Republic – one of many three competing powers in The Expanse, together with the United Nations (based mostly on Earth) and the Belt.
In early season 2 of The Expanse Deimos is destroyed with nuclear missiles in a “moon for a moon” retaliatory strike by the United Nations (Earth) after the Martian assault cruiser destroyed Earth’s analysis base on Saturn’s moon Phoebe together with the ensuing destruction of the moon itself. The destruction of Deimos killed 17 Martians and the moon disintegrated forming the “Deimos Ring” round Mars.
