WORLDWALKTOI-715 b
A super-Earth in the habitable zone of a red dwarf, found by TESS in 2024. Its year lasts about 19 days. It sits where a planet could be warm enough for liquid water, in the so-called habitable zone.

What it would be like in Worldwalk imagined
Nobody has seen the surface of TOI-715 b. The game builds it from the real numbers above: you land on frosty rock and snowfields.
- Air: N₂ (nitrogen), CO₂ (carbon dioxide) · a guess. Surface pressure: 1.5 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.
