WORLDWALKGJ 143 b
GJ 143 b is a hot water-rich world orbiting an orange star 53.2 ly away. A year there lasts 35.6 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 GJ 143 b. The game builds it from the real numbers above: you land on hot, steamy shores of a water world.
- Air: H₂O (water vapor) steam, N₂ (nitrogen) · a guess. Surface pressure: 7.3 bar.
- A 70 kg explorer would feel like 233 kg.
- A jump that clears 50 cm on Earth would reach about 15 cm.
- Every step is hard work: your legs carry far more than your body weight.
- The air is about 7 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.
