Mars (or Sol IV) is an inhabited planet belonging to the United Federation of Planets. It is located in the Sol system, which is in the Sol Sector of the Alpha Quadrant. The planet's name originates from a figure in Earth's Roman mythology.
Mars has been inhabited by humans since the early 22nd century, although a number outposts on the planet preceded the first colonies from as early 2069.
The Utopia Planitia Fleet Yards are in orbit of Mars.
Mars is a Class K planet which orbits Sol between Earth and the asteroid belt. Mars is just over half the size of the Sol system's prime planet, and it was the first planet in the system to be terraformed, enabling the planet to support human life. The first human colony was established on Mars in 2103, forty years after Zefram Cochrane's first warp flight.
Mars has two moons, Phobos and Deimos.
Work in progress.
