WORLDWALKGJ 625 b
GJ 625 b is a warm super-Earth orbiting a red dwarf star 21.1 ly away. A year there lasts 14.6 days. It was found using the radial velocity method: it makes its star wobble. Note: its size is estimated from its mass, only a minimum mass is known.
What it would be like in Worldwalk imagined
Nobody has seen the surface of GJ 625 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: 0.87 bar.
- A 70 kg explorer would feel like 89 kg.
- A jump that clears 50 cm on Earth would reach about 39 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.
