Ceres (designated 1 Ceres) is the largest known asteroid and the only dwarf planet in the inner solar system, and the first asteroid discovered by humanity. It lies in the asteroid belt.

Ceres Station

Ceres is the site of Ceres station, a space station that was one of the first sites of human colonization. Half a generation after humanity arrived there, Tycho Manufacturing managed to spin up the asteroid, which gave it a gravity of 0.3 g. The station has tens of thousands of kilometers of tunnels.

As the most important port in the Belt, the station has a population of approximately six million permanent residents with an extra one million transiting through at any given time. 800 - 1000 ships are docked on Ceres every day.

Ceres Station was initially governed by the UN, and station security was handled by the private security firm Star Helix Security.

After the Eros incident Books • TV, governorship of the station was given to the OPA.

The gravity on Ceres is not provided by its own mass but is spin gravity. The level of gravity changes with each level and there is a noticeable Coriolis Effect.

Transportation is provided by an extensive tube train network.

Battle for Ceres Station

Main article: Ceres Offensive

Certainly a misnomer, the "battle" was a well planned evacuation by the Free Navy of Marco Inaros Books • TV. Expecting a large defensive standoff and assault, the UN Navy, Martian fleet, and OPA loyalist burned into Ceres hard, only to find the station abandoned and there for the taking. The route from Ceres had caught the Consolidated Fleet so off guard, their automatic instinct was that it was a trap. With zero armed resistance, and a home security taskforce eager to surrender, the battle for Ceres Station never actually happened. James Holden Books • TV and the crew of the Rocinante Books • TV were present and equally taken aback by Inaros's choice to abandon the station.

Trivia

  • Ceres is the Roman goddess of Agriculture, who in turn is based on Greek goddess Demeter. In fact, the word cereal is derived from Ceres.
  • As per the NASA science video above, it is estimated that Ceres has a composition of up to 30% water or even more.
  • In the world of The Expanse, Ceres is a port city, outfitted with thrusters, put into a spin, creating a centrifugal gravity.
  • Researchers are uncertain how the planets have acquired their angular momentum, and how to change it over time is a difficult problem, due to its massive size
  • According to NASA video above, Mars has strip-mined Ceres bare of its ice to terraform the red planet.
  • Other material from the asteroid belt that could be mined are titanium, platinum and other precious metals.
  • People live inside the planet, upside down, so "up" is towards the center of the asteroid and "down" is towards the surface from within.
