Sol system
The setting of The Expanse from Leviathan Wakes onward: one Solar System holding a crowded Earth under the UN, an independent military Mars, and the working stations and asteroids of the Belt.
The Sol system is the Solar System. Humanity has spread across it without ever leaving it: thirty billion people on a crowded Earth governed by the United Nations, a disciplined independent republic on Mars, and a scattered population of Belters working the asteroids, moons, and stations of the outer planets. Water, air, and ore move constantly among those three economies, hauled by ships like the ice freighter Canterbury, where James Holden serves. Every border is a political one, because physically it is all one system: the same Sun and the same planets known today, settled hard and unevenly over centuries of expansion.
