WORLDWALKHD 25463 c
HD 25463 c is a scorching super-Earth orbiting a bright white-yellow star 148.8 ly away. A year there lasts 3 days. It was found using the transit method: it dims its star as it passes in front.
What it would be like in Worldwalk imagined
Nobody has seen the surface of HD 25463 c. 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: 0.004 bar.
- A 70 kg explorer would feel like 163 kg.
- A jump that clears 50 cm on Earth would reach about 22 cm.
- Every step is hard work: your legs carry far more than your body weight.
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.
