K2-166 b

K2-166 b is a scorching large super-Earth orbiting a Sun-like star 1,555 ly away. A year there lasts 8.5 days. It was found using the transit method: it dims its star as it passes in front. 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 mass is estimated from its size.

What it would be like in Worldwalk imagined

Nobody has seen the surface of K2-166 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.
