What it would be like in Worldwalk imagined
Nobody has seen the surface of HD 260655 b. The game builds it from the real numbers above: you land on dry, dusty desert rock.
- Air: thin CO₂ (carbon dioxide), N₂ (nitrogen) · a guess. Surface pressure: 0.87 bar.
- A 70 kg explorer would feel like 97 kg.
- A jump that clears 50 cm on Earth would reach about 36 cm.
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.
