Kepler-22 b
Kepler-22 b is a confirmed sub-Neptune exoplanet 635 ly from Earth in the constellation Cygnus, discovered in 2011 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-22 b, you would weigh about 106% more than you do on Earth. Its yellow, Sun-like star looks about the same size as ours, bathing the surface in warm white light. A year passes in just 290 days, and at an estimated 6°C (43°F) it is cold.

If your children grew up herea playful thought experiment
Heavier than home, at 2.1 times Earth's gravity. A child would end up markedly shorter and powerfully built, about 0.87x as tall as on Earth: a 5 ft 10 in adult could stand nearer 5 ft 1 in. Bones, muscle, and heart would all grow heavier just to stand and move.
- Bones
- Thick and dense
- More weight to bear forces the skeleton to grow denser and stronger all through childhood.
- Heart
- Large and powerful
- Pushing blood upward against stronger gravity demands a bigger, harder-working heart.
- Movement
- Low and deliberate
- A fall under this gravity lands hard, so movement stays slow, planted, and careful.
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 6°C (43°F), sound would travel close to its Earth speed, so your voice would sound much as it does on Earth. The real atmosphere is unknown.
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 temperatures near 6°C (43°F) fall in the range where liquid water is at least possible.
- !Noticeably heavy, 2.1 times Earth's gravity.
- A high Earth-similarity index of 0.81, among the more Earth-like worlds known.

What is the gravity on Kepler-22 b?
Kepler-22 b's surface gravity is about 2.1 times Earth's.
How much would you weigh on Kepler-22 b?
Someone who weighs 150 pounds on Earth would weigh about 310 pounds on Kepler-22 b.
How far is Kepler-22 b from Earth?
Kepler-22 b lies about 635 light-years from Earth.
How long would it take to get to Kepler-22 b?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 990,097 years.
How hot is Kepler-22 b?
Kepler-22 b's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about 6°C (43°F).
Is Kepler-22 b habitable?
Kepler-22 b orbits near its star's habitable zone, the range of distances where liquid water could be stable, and its Earth-similarity index is 0.81. That makes it worth studying, but it is not evidence of life: we have no measurement of its atmosphere, water, or surface.
How long is a year on Kepler-22 b?
Kepler-22 b completes one orbit of its star in 290 days.
