EPIC 211822797 b
EPIC 211822797 b is a confirmed sub-Neptune exoplanet 607 ly from Earth in the constellation Cancer, discovered in 2016 by K2.
Transit: spotted by the tiny, repeating dip in its star’s light each time the planet crosses in front of it.
Standing on EPIC 211822797 b, you would weigh roughly about 18% more than you do on Earth. Its orange dwarf looks 4.9× 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 21 days, and at an estimated 158°C (316°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 noticeably higher and reedier.
Assuming Earth-like air at this world's temperature of about 158°C (316°F), sound would travel roughly 22% 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 158°C (316°F), well above anything you would call comfortable.
- Surface gravity is close to Earth's, about 1.18 times, so you would move much as you do here.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
