GJ 667 C b
GJ 667 C b is a confirmed sub-Neptune exoplanet 23.6 ly from Earth in the constellation Scorpius, discovered in 2012 by La Silla Observatory.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
Standing on GJ 667 C b, you would weigh roughly about 12% more than you do on Earth. 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 7.2 days.
What these mean: surface gravity · tidal locking · equilibrium temperature
If your children grew up herea playful thought experiment
Gravity close to Earth's, at about 1.1 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 115°C (240°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.

- Surface gravity is close to Earth's, at least 1.12 times, so you would move much as you do here.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
