WORLDWALKGJ 3378 b
GJ 3378 b is a temperate super-Earth orbiting a red dwarf star 25.2 ly away. A year there lasts 21.5 days. It was found using the radial velocity method: it makes its star wobble. Its temperature could allow liquid water, which makes it a habitable-zone candidate, not a confirmed habitable world. Note: its size is estimated from its mass, only a minimum mass is known. 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 GJ 3378 b. The game builds it from the real numbers above: you land on dry, dusty desert rock.
- Air: thin CO₂ (carbon dioxide), N₂ (nitrogen) · a guess. Surface pressure: 0.88 bar.
- A 70 kg explorer would feel like 92 kg.
- A jump that clears 50 cm on Earth would reach about 38 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.
