G 264-012 c
G 264-012 c is a confirmed sub-Neptune 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 c, you would weigh roughly about 21% more than you do on Earth. Its red dwarf looks 5.8× 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 8.1 days, and at an estimated 114°C (237°F) it is warm.

If your children grew up herea playful thought experiment
Gravity close to Earth's, at about 1.2 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 noticeably higher and reedier.
Assuming Earth-like air at this world's temperature of about 114°C (237°F), sound would travel roughly 16% faster than on Earth, so your voice would sound noticeably higher and reedier. The real atmosphere is unknown, so this is a best guess.

- !Persistently hot at around 114°C (237°F), well above anything you would call comfortable.
- Surface gravity is close to Earth's, at least 1.21 times, so you would move much as you do here.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
