Kepler-444 e

Kepler-444 e is a confirmed rocky exoplanet 119 ly from Earth in the constellation Lyra, discovered in 2015 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-444 e, you would weigh about 66% less than you do on Earth. Its orange dwarf looks 10.8× 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 7.7 days, and at an estimated 454°C (849°F) it is furnace-hot.

If your children grew up herea playful thought experiment
EARTH HEIGHT≈ 1.2xEARTH-RAISEDRAISED HERE
about 1.2x taller than on Earth · a 5 ft 10 in adult could stand nearer 7 ft 3 in

Low gravity, 0.34 times Earth's. A child who grew up here could become strikingly tall and lightly built, about 1.2x taller than on Earth: a 5 ft 10 in adult could stand nearer 7 ft 3 in, with long limbs and slender bones.

Bones
Light and slender
With little weight to carry, the growing skeleton lays down far less bone, the way astronauts' bones thin in months of low gravity.
Heart
Unhurried
With less weight pulling blood down toward the feet, the heart has far less work to do.
Movement
Bounding and springy
So little weight means each step would carry the body up and forward in long, floating strides.

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 454°C (849°F), sound would travel roughly 59% 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.

The journey
Cosmic travel advisory
☆☆☆☆
Do not travel
  • !Furnace-hot at around 454°C (849°F), with no liquid water and no shade anywhere.
  • !Far too little gravity, 0.34 times Earth's, to hold a breathable atmosphere: effectively an airless vacuum.
  • !Its star delivers about 81 times the sunlight Earth gets, a blinding, sterilizing glare.
  • !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
