WORLDWALKGJ 724 b
GJ 724 b is a hot large super-Earth orbiting a red dwarf star 55.3 ly away. A year there lasts 5.1 days. It was found using the radial velocity method: it makes its star wobble. Planets this size may be wrapped in thick gas; the game imagines it as a solid or water world you can walk on. 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 724 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: 0.46 bar.
- A 70 kg explorer would feel like 70 kg.
- A jump that clears 50 cm on Earth would reach about 50 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.
