WORLDWALKKOI-55 c
KOI-55 c is a scorching Earth-size planet orbiting a hot blue-white star 4,015 ly away. A year there lasts 8 hours. It was found using the brightness changes it causes as it orbits.

What it would be like in Worldwalk imagined
Nobody has seen the surface of KOI-55 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: almost none.
- A 70 kg explorer would feel like 61 kg.
- A jump that clears 50 cm on Earth would reach about 57 cm.
- 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.
