Kepler-1512 b
Kepler-1512 b is a confirmed rocky exoplanet 528 ly from Earth in the constellation Cygnus, discovered in 2016 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-1512 b, you would weigh roughly about 26% 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 49°C (120°F) it is warm.

If your children grew up herea playful thought experiment
Gravity close to Earth's, at about 1.3 times. A child would grow up much as they would back home.
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 much as it does on Earth.
Assuming Earth-like air at this world's temperature of about 49°C (120°F), sound would travel roughly 6% faster than on Earth, so your voice would sound much as it does on Earth. The real atmosphere is unknown, so this is a best guess.

- !Persistently hot at around 49°C (120°F), well above anything you would call comfortable.
- Surface gravity is close to Earth's, about 1.26 times, so you would move much as you do here.
- A high Earth-similarity index of 0.81, among the more Earth-like worlds known.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
