Artificial gravity in Terra Expanse is produced through rotation, acceleration, or the natural gravity of a celestial body. Belt settlements do not use gravity generators or other physics-breaking technology. Large inhabited asteroids therefore combine their natural gravity with rotating habitat sections where higher effective gravity is needed.
Ceres itself provides only weak surface gravity. Most major residential, commercial, medical, and administrative districts are therefore built inside large rotating habitat drums and ring-sections excavated beneath the surface. These structures rotate independently of Ceres and provide stable partial gravity for everyday life. Older tunnels, mines, docks, freight shafts, and maintenance areas may remain close to natural Ceres gravity, creating noticeable differences between districts.
Vesta retains low natural gravity across most industrial and exterior facilities. Ship construction, cargo handling, and heavy engineering often benefit from this environment, so many yards deliberately remain low-g. Crew habitats, medical areas, offices, and long-term residential sections use smaller rotating modules or habitation rings to provide more comfortable gravity. Workers routinely move between different gravity levels during a shift.
Pallas is too small for comfortable natural gravity in most inhabited areas. The settlement relies heavily on rotating internal habitats and attached spin sections. Commercial, residential, and hospitality districts maintain relatively consistent partial gravity, while docks, warehouses, transit hubs, and older industrial sections may operate at much lower gravity.
Hygiea combines weak natural gravity with practical rotating habitats. Mining and processing zones usually retain low gravity because it reduces the energy required to move heavy material. Residential compounds and medical facilities provide higher effective gravity through rotating habitation structures. Gravity standards are less uniform than on Ceres or Pallas, reflecting Hygiea’s fragmented and industrial character.
