WORLDWALKAU Mic d
AU Mic d is a frozen Earth-size planet orbiting a red dwarf star 31.7 ly away. A year there lasts 12.7 days. It was found using tiny timing shifts in a neighboring planet's transits. Note: its temperature is unknown, so the game assumes one.
What it would be like in Worldwalk imagined
Nobody has seen the surface of AU Mic d. 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: 0.15 bar.
- A 70 kg explorer would feel like 71 kg.
- A jump that clears 50 cm on Earth would reach about 50 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.
