K2-349 b
K2-349 b is a confirmed rocky exoplanet 1,479 ly from Earth in the constellation Virgo, discovered in 2021 by K2.
Transit: spotted by the tiny, repeating dip in its star’s light each time the planet crosses in front of it.
Standing on K2-349 b, you would weigh roughly about 30% more than you do on Earth. Bathing the surface in amber-orange light. A year passes in just 9.0 days, and at an estimated 245°C (473°F) it is blistering.

If your children grew up herea playful thought experiment
A little heavier than home, at about 1.3 times Earth's gravity. A child raised here would likely grow a little shorter and sturdier than their Earth-raised parents, about 0.95x as tall as on Earth: a 5 ft 10 in adult could stand nearer 5 ft 6 in, with denser bones.
- Bones
- Thick and dense
- More weight to bear forces the skeleton to grow denser and stronger all through childhood.
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 245°C (473°F), sound would travel roughly 34% 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 245°C (473°F), far too hot for liquid water on the surface.
- Surface gravity is close to Earth's, about 1.30 times, so you would move much as you do here.
