WORLDWALKK2-223 c
K2-223 c is a scorching super-Earth orbiting a Sun-like star 647.8 ly away. A year there lasts 4.6 days. 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 K2-223 c. 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: 0.002 bar.
- A 70 kg explorer would feel like 148 kg.
- A jump that clears 50 cm on Earth would reach about 24 cm.
- Every step is hard work: your legs carry far more than your body weight.
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.
