TOI-654.01

TOI-654.01 is a hot large super-Earth orbiting a red dwarf star 188.4 ly away. A year there lasts 1.5 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.

What it would be like in Worldwalk imagined

Nobody has seen the surface of TOI-654.01. 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.
