WORLDWALKProxima Cen b
The closest known exoplanet, just 4.2 light-years away. It sits in its red dwarf's habitable zone, but the star blasts it with frequent flares and it is probably tidally locked. It sits where a planet could be warm enough for liquid water, in the so-called habitable zone.
What it would be like in Worldwalk imagined
Nobody has seen the surface of Proxima Cen b. The game builds it from the real numbers above: you land on frosty rock and snowfields.
- Air: N₂ (nitrogen), CO₂ (carbon dioxide) · a guess. Surface pressure: 1.31 bar.
- A 70 kg explorer would feel like 71 kg.
- A jump that clears 50 cm on Earth would reach about 49 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.
