Kepler-370 c
Kepler-370 c is a confirmed sub-Neptune exoplanet 3,809 ly from Earth in the constellation Cygnus, discovered in 2014 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-370 c, you would weigh roughly about 18% more than you do on Earth. Its yellow, Sun-like star looks 6.4× wider than ours, bathing the surface in warm white 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 19 days, and at an estimated 374°C (705°F) it is blistering.

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 high and thin, almost cartoonish.
Assuming Earth-like air at this world's temperature of about 374°C (705°F), sound would travel roughly 50% faster than on Earth, so your voice would sound high and thin, almost cartoonish. The real atmosphere is unknown, so this is a best guess.

- !Blistering at about 374°C (705°F), far too hot for liquid water on the surface.
- Surface gravity is close to Earth's, about 1.18 times, so you would move much as you do here.
- !Its star delivers about 54 times the sunlight Earth gets, a blinding, sterilizing glare.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.

What is the gravity on Kepler-370 c?
Kepler-370 c's surface gravity is about 1.2 times Earth's, estimated from its size.
How much would you weigh on Kepler-370 c?
Someone who weighs 150 pounds on Earth would weigh about 177 pounds on Kepler-370 c.
How far is Kepler-370 c from Earth?
Kepler-370 c lies about 3,809 light-years from Earth.
How long would it take to get to Kepler-370 c?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 5.9 million years.
How hot is Kepler-370 c?
Kepler-370 c's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about 374°C (705°F).
How long is a year on Kepler-370 c?
Kepler-370 c completes one orbit of its star in 19 days.
