WORLDWALKK2-138 d
K2-138 d is a hot large super-Earth orbiting a Sun-like star 660.7 ly away. A year there lasts 5.4 days. It was found using the transit method: it dims its star as it passes in front. Planets this size may be wrapped in thick gas; the game imagines it as a solid or water world you can walk on.
What it would be like in Worldwalk imagined
Nobody has seen the surface of K2-138 d. The game builds it from the real numbers above: you land on bare, cratered rock with no air.
- Air: None (bare rock). Surface pressure: almost none.
- A 70 kg explorer would feel like 97 kg.
- A jump that clears 50 cm on Earth would reach about 36 cm.
- With almost no air, a hammer and a feather fall side by side, and sound cannot travel.
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.
