Ross 128 b

Orbits one of the quietest red dwarfs nearby, so it may escape the violent flares that threaten planets like Proxima b. It sits where a planet could be warm enough for liquid water, in the so-called habitable zone.

What it would be like in Worldwalk imagined

Nobody has seen the surface of Ross 128 b. The game builds it from the real numbers above: you land on dry, dusty desert rock.

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.
