WORLDWALKKepler-198 d
Kepler-198 d is a scorching super-Earth orbiting a Sun-like star 1,616 ly away. A year there lasts 1.3 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-198 d. The game builds it from the real numbers above: you land on sulfur volcanoes and yellow lava.
- Air: SO₂ (sulfur dioxide), volcanic · a guess. Surface pressure: 0.009 bar.
- A 70 kg explorer would feel like 88 kg.
- A jump that clears 50 cm on Earth would reach about 40 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.
