GJ 3929 c

GJ 3929 c is a temperate water-rich world orbiting a red dwarf star 51.6 ly away. A year there lasts 15 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 3929 c. The game builds it from the real numbers above: you land on a deep global ocean with rocky islands.

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.
