AU Mic c

AU Mic c is a hot water-rich world orbiting a red dwarf star 31.7 ly away. A year there lasts 18.9 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 AU Mic c. 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: 5.8 bar.
A 70 kg explorer would feel like 130 kg.
A jump that clears 50 cm on Earth would reach about 27 cm.
Every step is hard work: your legs carry far more than your body weight.
The air is about 6 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.

Sizes, masses, temperatures and orbits come from the NASA Exoplanet Archive (Planetary Systems Composite table). Values marked estimated are calculated from the other measurements; the surface and air are imagined for the game.
