Mars

Not to be confused with Marz, a city of United Enterprise.

Mars. It's also called the Red Planet, but let's call it Mars. So Mars, as hostile as it may be, is actually the second most habitable planet in the Solar System (besides Earth). It has freshwater at the poles, canyons, and even the biggest mountain in the entire Solar System. Mars also has a similar day to Earth, around 24 hours. Mars has two moons, Phobos and Deimos, but they're kinda small and insignificant, although Phobos is gonna come crashing into Mars sooner or later. Deimos is just gonna float away. Mars is also the fourth-brightest object in the sky of Earth, with a brightness of -2.94.
