Ceres, located in the Main Asteroid Belt between the orbits of Mars and Jupiter, is
the largest known asteroid (~940km in diameter) and the only dwarf planet in the Inner Solar system.
In the universe of
The Expanse TV series (a political sci-fi drama set in mid-24th century when humans have colonized the entire Solar system) Ceres acts as the de facto capital for the Belt - one of the three competing powers in
The Expanse, along with the United Nations (based on Earth) and Mars.
Ceres naturally has a gravity of 0.029g (2,9% of the gravity force on Earth), but in the universe of
The Expanse it has been artificially spun up to 0.3g of centrifugal force (so the "gravity" points in the opposite direction, not towards the center of the planet). There is a population of around 6 million in
Ceres Station which consists of tens of thousands of kilometers of tunnels bored deep into Ceres.
Ceres Station is the most important spaceport in the Belt, 800 to 1'000 ships are docked on Ceres every day, so along with the 6 million permanent residents there are an extra one million transiting through at any given time.
Ceres Station was initially governed by the United Nations, but during season 1 of the show
Outer Planets Alliance (
OPA, a fractured sociopolitical movement trying to unite the Belt) takes control.
The life on Ceres is depicted in season 1 and season 6 of The Expanse. Here you can view some of the best shots from locations on
