WORLDWALKKepler-390 c
Kepler-390 c is a hot small rocky planet orbiting an orange star 1,420 ly away. Its star system has 2 stars. A year there lasts 13.1 days. It was found using the transit method: it dims its star as it passes in front. Note: its mass is estimated from its size.
What it would be like in Worldwalk imagined
Nobody has seen the surface of Kepler-390 c. The game builds it from the real numbers above: you land on dry, dusty desert rock.
- Air: thin CO₂ (carbon dioxide), N₂ (nitrogen) · a guess. Surface pressure: 0.27 bar.
- A 70 kg explorer would feel like 47 kg.
- A jump that clears 50 cm on Earth would reach about 74 cm.
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.
