WORLDWALKGJ 3473 b
GJ 3473 b is a hot super-Earth orbiting a red dwarf star 89.3 ly away. Its star system has 2 stars. A year there lasts 1.2 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 GJ 3473 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 82 kg.
- A jump that clears 50 cm on Earth would reach about 43 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.
