WORLDWALKTOI-700 d
The first Earth-size planet in a habitable zone found by NASA's TESS mission (2020). 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-700 d. The game builds it from the real numbers above: you land on rocky land with shallow seas.
- Air: N₂ (nitrogen), CO₂ (carbon dioxide), H₂O (water vapor) · a guess. Surface pressure: 1.41 bar.
- A 70 kg explorer would feel like 84 kg.
- A jump that clears 50 cm on Earth would reach about 41 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.

Sizes, masses, temperatures and orbits come from the NASA Exoplanet Archive (Planetary Systems Composite table). Values marked estimated are calculated from the other measurements; the surface and air are imagined for the game.
