Kepler-49 c
Kepler-49 c is a confirmed sub-Neptune exoplanet 1,015 ly from Earth in the constellation Cygnus, discovered in 2012 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-49 c, you would weigh about 40% more than you do on Earth. Its orange dwarf looks 7.9× wider than ours, bathing the surface in amber-orange 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 11 days, and at an estimated 170°C (338°F) it is blistering.

If your children grew up herea playful thought experiment
A little heavier than home, at 1.4 times Earth's gravity. A child raised here would likely grow a little shorter and sturdier than their Earth-raised parents, about 0.93x as tall as on Earth: a 5 ft 10 in adult could stand nearer 5 ft 5 in, with denser bones.
- Bones
- Thick and dense
- More weight to bear forces the skeleton to grow denser and stronger all through childhood.
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 noticeably higher and reedier.
Assuming Earth-like air at this world's temperature of about 170°C (338°F), sound would travel roughly 24% faster than on Earth, so your voice would sound noticeably higher and reedier. The real atmosphere is unknown, so this is a best guess.

- !Persistently hot at around 170°C (338°F), well above anything you would call comfortable.
- Surface gravity is close to Earth's, 1.40 times, so you would move much as you do here.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.

What is the gravity on Kepler-49 c?
Kepler-49 c's surface gravity is about 1.4 times Earth's.
How much would you weigh on Kepler-49 c?
Someone who weighs 150 pounds on Earth would weigh about 210 pounds on Kepler-49 c.
How far is Kepler-49 c from Earth?
Kepler-49 c lies about 1,015 light-years from Earth.
How long would it take to get to Kepler-49 c?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 1.6 million years.
How hot is Kepler-49 c?
Kepler-49 c's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about 170°C (338°F).
How long is a year on Kepler-49 c?
Kepler-49 c completes one orbit of its star in 11 days.
