Kepler-1966 b

Kepler-1966 b is a hot Earth-size planet orbiting an orange star 1,581 ly away. A year there lasts 8.6 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.

What it would be like in Worldwalk imagined

Nobody has seen the surface of Kepler-1966 b. The game builds it from the real numbers above: you land on bare, cratered rock with no air.

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.
