Kepler-1634 b
Kepler-1634 b is a confirmed sub-Neptune exoplanet 2,013 ly from Earth in the constellation Cygnus, discovered in 2016 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-1634 b, you would weigh roughly almost exactly what you weigh on Earth. Its yellow, Sun-like star looks 0.85× as wide as ours, bathing the surface in warm white light. A year here lasts 375 days, and it sits squarely in the habitable zone, among the more Earth-like worlds known.

If your children grew up herea playful thought experiment
Gravity close to Earth's, at about 1.0 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 much as it does on Earth.
Assuming Earth-like air at this world's temperature of about 9°C (48°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 9°C (48°F) fall in the range where liquid water is at least possible.
- Surface gravity is close to Earth's, about 1.01 times, so you would move much as you do here.
- It orbits within the habitable zone, where a world could in principle hold liquid water.

What is the gravity on Kepler-1634 b?
Kepler-1634 b's surface gravity is about 1.0 times Earth's, estimated from its size.
How much would you weigh on Kepler-1634 b?
Someone who weighs 150 pounds on Earth would weigh about 152 pounds on Kepler-1634 b.
How far is Kepler-1634 b from Earth?
Kepler-1634 b lies about 2,013 light-years from Earth.
How long would it take to get to Kepler-1634 b?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 3.1 million years.
How hot is Kepler-1634 b?
Kepler-1634 b's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about 9°C (48°F).
Is Kepler-1634 b habitable?
Kepler-1634 b orbits inside its star's habitable zone, the range of distances where liquid water could be stable, and its Earth-similarity index is 0.65. 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-1634 b?
Kepler-1634 b completes one orbit of its star in 375 days.
