Kepler-268 c
Kepler-268 c is a confirmed sub-Neptune exoplanet 2,778 ly from Earth in the constellation Lyra, 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-268 c, you would weigh roughly almost exactly what you weigh on Earth. Its yellow-white star looks 3.3× wider than ours, bathing the surface in bright white light. A year passes in just 83 days, and at an estimated 198°C (388°F) it is blistering.

If your children grew up herea playful thought experiment
Gravity close to Earth's, at about 1.00 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 198°C (388°F), sound would travel roughly 28% 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.
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.
- !Blistering at about 198°C (388°F), far too hot for liquid water on the surface.
- Surface gravity is close to Earth's, about 1.00 times, so you would move much as you do here.

What is the gravity on Kepler-268 c?
Kepler-268 c's surface gravity is about 1.00 times Earth's, estimated from its size.
How much would you weigh on Kepler-268 c?
Someone who weighs 150 pounds on Earth would weigh about 150 pounds on Kepler-268 c.
How far is Kepler-268 c from Earth?
Kepler-268 c lies about 2,778 light-years from Earth.
How long would it take to get to Kepler-268 c?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 4.3 million years.
How hot is Kepler-268 c?
Kepler-268 c's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about 198°C (388°F).
