TOI-2322 c
TOI-2322 c is a confirmed sub-Neptune exoplanet 195 ly from Earth in the constellation Volans, discovered in 2025 by Transiting Exoplanet Survey Satellite (TESS).
Transit: spotted by the tiny, repeating dip in its star’s light each time the planet crosses in front of it.
Standing on TOI-2322 c, you would weigh about 415% more than you do on Earth. Its orange dwarf looks 4.9× wider than ours, bathing the surface in amber-orange light. It is likely tidally locked, so that sun never moves in the sky: one hemisphere in endless day, the other in permanent night. A year passes in just 20 days, and at an estimated 224°C (435°F) it is blistering.

If your children grew up herea playful thought experiment
Beyond about four times Earth's gravity, a growing child's skeleton could not carry its own weight. A human body simply could not develop here, even sheltered indoors. The shape below is only where the trend points before biology gives out: short, and impossibly dense.
- Bones
- Thick and dense
- More weight to bear forces the skeleton to grow denser and stronger all through childhood.
- Heart
- Large and powerful
- Pushing blood upward against stronger gravity demands a bigger, harder-working heart.
A playful thought experiment from this world’s gravity, not a prediction about any real person. No human has ever grown up off Earth, so no one truly knows; the direction (taller in low gravity, shorter and stockier in high) follows how growing bodies respond to weight.
Hear how a voice sounds herea computed acoustic demo
Your voice would sound high and thin, almost cartoonish.
Assuming Earth-like air at this world's temperature of about 224°C (435°F), sound would travel roughly 31% faster than on Earth, so your voice would sound high and thin, almost cartoonish. The real atmosphere is unknown, so this is a best guess.

- !Blistering at about 224°C (435°F), far too hot for liquid water on the surface.
- !Gravity is 5.2 times Earth's, near the limit at which a person can stand or walk at all.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
