WORLDWALKGl 49 b
Gl 49 b is a hot water-rich world orbiting a red dwarf star 32.1 ly away. Its star system has 2 stars. A year there lasts 13.9 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 Gl 49 b. The game builds it from the real numbers above: you land on hot, steamy shores of a water world.
- Air: H₂O (water vapor) steam, N₂ (nitrogen) · a guess. Surface pressure: 6.8 bar.
- A 70 kg explorer would feel like 79 kg.
- A jump that clears 50 cm on Earth would reach about 45 cm.
- The air is about 7 times denser than at sea level on Earth: thick enough to slow a falling 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.
