G 264-012 b
G 264-012 b is a confirmed rocky exoplanet 52.2 ly from Earth in the constellation Cepheus, discovered in 2021 by Calar Alto Observatory.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
Standing on G 264-012 b, you would weigh roughly about 29% more than you do on Earth. Its red dwarf looks 13.4× wider than ours, bathing the surface in deep 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 2.3 days, and at an estimated 314°C (597°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 7 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 314°C (597°F), sound would travel roughly 43% 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 314°C (597°F), far too hot for liquid water on the surface.
- Surface gravity is close to Earth's, at least 1.29 times, so you would move much as you do here.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
