GJ 9404 b

GJ 9404 b is a hot large super-Earth orbiting a red dwarf star 77.9 ly away. A year there lasts 13.5 days. It was found using the radial velocity method: it makes its star wobble. 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.

What it would be like in Worldwalk imagined

Nobody has seen the surface of GJ 9404 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.
