WORLDWALKK2-398 b
K2-398 b is a frozen water-rich world orbiting a Sun-like star 1,980 ly away. A year there lasts 6.4 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. Note: its mass is estimated from its size, its temperature is unknown, so the game assumes one.
What it would be like in Worldwalk imagined
Nobody has seen the surface of K2-398 b. The game builds it from the real numbers above: you land on a frozen shell of ice.
- Air: thin N₂ (nitrogen) · a guess. Surface pressure: 0.11 bar.
- A 70 kg explorer would feel like 79 kg.
- A jump that clears 50 cm on Earth would reach about 45 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.
