WORLDWALKLHS 1815 b
LHS 1815 b is a hot Earth-size planet orbiting a red dwarf star 97.3 ly away. A year there lasts 3.8 days. It was found using the transit method: it dims its star as it passes in front.

What it would be like in Worldwalk imagined
Nobody has seen the surface of LHS 1815 b. The game builds it from the real numbers above: you land on bare, cratered rock with no air.
- Air: None (bare rock). Surface pressure: almost none.
- A 70 kg explorer would feel like 93 kg.
- A jump that clears 50 cm on Earth would reach about 38 cm.
- With almost no air, a hammer and a feather fall side by side, and sound cannot travel.
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.
