Barnard b
Orbits Barnard's Star, one of our nearest neighbors at 6 light-years. It is smaller than Earth and too hot for liquid water.

What it would be like in Worldwalk imagined
Nobody has seen the surface of Barnard b. The game builds it from the real numbers above: you land on bare, cratered rock with no air.
- Air: None (bare rock). Surface pressure: almost none.
- A 70 kg explorer would feel like 40 kg.
- A jump that clears 50 cm on Earth would reach about 87 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.
