Kepler-1729 b

Kepler-1729 b is a hot large super-Earth orbiting a red dwarf star 1,879 ly away. A year there lasts 4.2 days. It was found using the transit method: it dims its star as it passes in front. 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 mass is estimated from its size.

What it would be like in Worldwalk imagined

Nobody has seen the surface of Kepler-1729 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.
