K2-136 d

K2-136 d is a confirmed rocky exoplanet 193 ly from Earth in the constellation Taurus, discovered in 2017 by K2.

ESI 0.61193 lyDiscovered in 2017 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 K2-136 d, you would weigh about 22% more than you do on Earth. Its orange dwarf looks 4.4× 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 26 days, and at an estimated 147°C (296°F) it is blistering.

Gravity close to Earth's, at 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 147°C (296°F), sound would travel roughly 21% faster than on Earth, so your voice would sound noticeably higher and reedier. The real atmosphere is unknown, so this is a best guess.

The journey
Cosmic travel advisory
★★★★
Recommended, with reservations
  • !Persistently hot at around 147°C (296°F), well above anything you would call comfortable.
  • Surface gravity is close to Earth's, 1.22 times, so you would move much as you do here.
  • !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
