WORLDWALKKepler-438 b
Kepler-438 b is a temperate Earth-size planet orbiting a red dwarf star 639.1 ly away. A year there lasts 35.2 days. It was found using the transit method: it dims its star as it passes in front. Its temperature could allow liquid water, which makes it a habitable-zone candidate, not a confirmed habitable world. Note: its mass is estimated from its size. 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 Kepler-438 b. The game builds it from the real numbers above: you land on dry, dusty desert rock.
- Air: thin CO₂ (carbon dioxide), N₂ (nitrogen) · a guess. Surface pressure: 0.41 bar.
- A 70 kg explorer would feel like 81 kg.
- A jump that clears 50 cm on Earth would reach about 43 cm.
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.
