GJ 667 C g
GJ 667 C g is a confirmed sub-Neptune exoplanet 23.6 ly from Earth in the constellation Scorpius, discovered in 2013 by La Silla Observatory.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
Standing on GJ 667 C g, you would weigh roughly about 16% more than you do on Earth. Bathing the surface in deep orange light. A year passes in just 256 days.

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 deep and slow, dropped to a low bass.
Assuming Earth-like air at this world's temperature of about -155°C (-248°F), sound would travel roughly 36% slower than on Earth, so your voice would sound deep and slow, dropped to a low bass. The real atmosphere is unknown, so this is a best guess.
A real voice sample, pitch-shifted (tempo held constant) to suggest the acoustics: a playful approximation, not a precise simulation. Voice: Lingua Libre / Vealhurl, CC BY-SA 4.0.
- Surface gravity is close to Earth's, at least 1.16 times, so you would move much as you do here.

What is the gravity on GJ 667 C g?
GJ 667 C g's surface gravity is at least 1.2 times Earth's, and possibly more: its mass is only a lower bound.
How much would you weigh on GJ 667 C g?
Someone who weighs 150 pounds on Earth would weigh at least 174 pounds on GJ 667 C g.
How far is GJ 667 C g from Earth?
GJ 667 C g lies about 23.6 light-years from Earth.
How long would it take to get to GJ 667 C g?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 36,848 years.
How long is a year on GJ 667 C g?
GJ 667 C g completes one orbit of its star in 256 days.
