GJ 3222 b

GJ 3222 b is a hot large super-Earth orbiting an orange star 59.5 ly away. Its star system has 2 stars. A year there lasts 10.7 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 3222 b. The game builds it from the real numbers above: you land on glowing iron-rich lava fields.

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.
