EPIC 249893012 b
EPIC 249893012 b is a confirmed sub-Neptune exoplanet 1,048 ly from Earth in the constellation Libra, discovered in 2020 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 EPIC 249893012 b, you would weigh about 130% more than you do on Earth. Its yellow, Sun-like star looks 36.0× wider than ours, bathing the surface in warm white 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 3.6 days, and at an estimated 1343°C (2449°F) it is hot enough to melt rock.

If your children grew up herea playful thought experiment
Heavier than home, at 2.3 times Earth's gravity. A child would end up markedly shorter and powerfully built, about 0.85x as tall as on Earth: a 5 ft 10 in adult could stand nearer 4 ft 11 in. Bones, muscle, and heart would all grow heavier just to stand and move.
- 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.
- Movement
- Low and deliberate
- A fall under this gravity lands hard, so movement stays slow, planted, and careful.
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 1343°C (2449°F), sound would travel roughly 137% 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.

- !At about 1343°C (2449°F), the daytime side glows: metals run liquid and any atmosphere is being torn away.
- !Gravity is 2.3 times Earth's, so every movement is a strain and a fall could be fatal.
- !Its star delivers about 1,037 times the sunlight Earth gets, a blinding, sterilizing glare.
- !Earth-similarity index 0.14: this world has almost nothing in common with our own.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
