GJ 682 b

GJ 682 b is a temperate water-rich world orbiting a red dwarf star 16.3 ly away. A year there lasts 17.5 days. It was found using the radial velocity method: it makes its star wobble. Its temperature could allow liquid water, which makes it a habitable-zone candidate, not a confirmed habitable world. Planets this size may be wrapped in thick gas; the game imagines it as a solid or water world you can walk on. Note: its size is estimated from its mass, only a minimum mass is known. 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 GJ 682 b. The game builds it from the real numbers above: you land on a deep global ocean with rocky islands.

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.
