K2-385 b

K2-385 b is a frozen super-Earth orbiting an orange star 1,372 ly away. A year there lasts 2.4 days. It was found using the transit method: it dims its star as it passes in front. 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 K2-385 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.
