GJ 341 b

GJ 341 b is a confirmed rocky exoplanet 34.1 ly from Earth in the constellation Carina, 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 GJ 341 b, you would weigh about 417% more than you do on Earth. Bathing the surface in deep orange light. A year passes in just 7.6 days, and at an estimated 356°C (673°F) it is blistering.

If your children grew up herea playful thought experiment
EARTH HEIGHT≈ 0.72xEARTH-RAISEDRAISED HERE
about 0.72x as tall as on Earth · a 5 ft 10 in adult could stand nearer 4 ft 2 in

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 356°C (673°F), sound would travel roughly 48% 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.

The journey
Cosmic travel advisory
☆☆☆☆
Do not travel
  • !Blistering at about 356°C (673°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.
