K2-366 b

K2-366 b is a frozen water-rich world orbiting a Sun-like star 606.5 ly away. A year there lasts 15.9 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, its temperature is unknown, so the game assumes one.

What it would be like in Worldwalk imagined

Nobody has seen the surface of K2-366 b. The game builds it from the real numbers above: you land on a frozen shell of ice.

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.
