WORLDWALKRoss 508 b
Ross 508 b is a temperate water-rich world orbiting a red dwarf star 36.6 ly away. A year there lasts 10.8 days. It was found using the radial velocity method: it makes its star wobble. Its temperature could allow liquid water, which makes it a habitable-zone candidate, not a confirmed habitable world. Planets this size may be wrapped in thick gas; the game imagines it as a solid or water world you can walk on. Note: its size is estimated from its mass, only a minimum mass is known. It sits where a planet could be warm enough for liquid water, in the so-called habitable zone.
What it would be like in Worldwalk imagined
Nobody has seen the surface of Ross 508 b. The game builds it from the real numbers above: you land on a deep ocean under a hydrogen sky.
- Air: Rich in H₂ (hydrogen), H₂O (water vapor) · a guess. Surface pressure: 13 bar.
- A 70 kg explorer would feel like 84 kg.
- A jump that clears 50 cm on Earth would reach about 42 cm.
- The air is about 13 times denser than at sea level on Earth: thick enough to slow a falling rock.
Pack the right suit. Choose 3 of 6 modules (cooling, heating, pressure hull, extra oxygen, radiation shield, jetpack), complete 3 surveys and get back to the lander before your oxygen runs out.
