WORLDWALKK2-85 b
K2-85 b is a scorching super-Earth orbiting an orange star 317.1 ly away. A year there lasts 16 hours. It was found using the transit method: it dims its star as it passes in front.

What it would be like in Worldwalk imagined
Nobody has seen the surface of K2-85 b. The game builds it from the real numbers above: you land on a molten surface of lava seas.
- Air: rock vapor · a guess. Surface pressure: almost none.
- A 70 kg explorer would feel like 114 kg.
- A jump that clears 50 cm on Earth would reach about 31 cm.
- Every step is hard work: your legs carry far more than your body weight.
- With almost no air, a hammer and a feather fall side by side, and sound cannot travel.
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.

Sizes, masses, temperatures and orbits come from the NASA Exoplanet Archive (Planetary Systems Composite table). Values marked estimated are calculated from the other measurements; the surface and air are imagined for the game.
