Loading contentMars is the fourth planet from the Sun, a cold desert world whose surface is colored red by iron-oxide ('rust') dust. It has a thin atmosphere, seasons, and polar caps of ice.
Mars hosts towering volcanoes — including Olympus Mons, the largest known volcano in the Solar System — and vast canyon systems. Channels carved long ago suggest liquid water once flowed there.
Beyond Earth, Mars is the most intensively explored planet, with orbiters, landers, and rovers studying its geology and climate and searching for signs of past habitability. It has two small moons, Phobos and Deimos.
How this connects across Asteria Star — scientific, cultural, and astrological links are kept separate.
