Caelum
The outer world
An inhabited world of dark seas, glacier light and life sheltered from the cold.
Explore this world01 / PLANETARY PROFILETHE PHYSICAL MODEL
A world with its own rules
Beyond Earth.
Caelum receives less stellar energy. A greenhouse atmosphere sustains water in protected regions while ice and fog define its farther horizons.
- Distance from Eldios
- 1.05 AU
- Orbital year
- ≈ 414 days
- Stellar energy
- 0.54 × Earth
- Radius
- 1.16 × Earth
- Estimated mass
- ≈ 1.73 × Earth
- Estimated surface gravity
- ≈ 1.29 × Earth
Working model: each radius is a chosen value; orbital distance does not determine planet size. Mass assumes an Earth-like rocky interior; surface gravity follows from mass and radius. These values are estimates, not observations. Diameter: ≈ 14,780 km. Mass–radius method ↗
THE VISUAL ARCHIVE / Caelum02 / THE LANDSCAPE
Nature, unfamiliar.
A cool outer world. A strong greenhouse effect is needed for protected liquid-water regions beneath icy horizons.
- Glassy ice arches
- Obsidian coastlines
- Sheltered dark seas
