Kepler-1994 b
Kepler-1994 b is a confirmed rocky exoplanet 789 ly from Earth in the constellation Cygnus, discovered in 2023 by Kepler.
Transit: spotted by the tiny, repeating dip in its star’s light each time the planet crosses in front of it.
Standing on Kepler-1994 b, you would weigh roughly about 67% less than you do on Earth. Its yellow, Sun-like star looks 18.1× 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 4.6 days, and at an estimated 759°C (1398°F) it is furnace-hot.

If your children grew up herea playful thought experiment
Low gravity, about 0.33 times Earth's. A child who grew up here could become strikingly tall and lightly built, about 1.2x taller than on Earth: a 5 ft 10 in adult could stand nearer 7 ft 3 in, with long limbs and slender bones.
- Bones
- Light and slender
- With little weight to carry, the growing skeleton lays down far less bone, the way astronauts' bones thin in months of low gravity.
- Heart
- Unhurried
- With less weight pulling blood down toward the feet, the heart has far less work to do.
- Movement
- Bounding and springy
- So little weight means each step would carry the body up and forward in long, floating strides.
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 759°C (1398°F), sound would travel roughly 89% 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.

- !Furnace-hot at around 759°C (1398°F), with no liquid water and no shade anywhere.
- !Far too little gravity, about 0.33 times Earth's, to hold a breathable atmosphere: effectively an airless vacuum.
- !Its star delivers about 268 times the sunlight Earth gets, a blinding, sterilizing glare.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
