GJ 486 b

GJ 486 b is a confirmed rocky exoplanet 26.3 ly from Earth in the constellation Virgo, discovered in 2021 by Calar Alto Observatory.

Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.

Standing on GJ 486 b, you would weigh about 67% more than you do on Earth. Its red dwarf looks 18.9× wider than ours, bathing the surface in deep 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 1.5 days, and at an estimated 423°C (794°F) it is blistering.

If your children grew up herea playful thought experiment
EARTH HEIGHT≈ 0.90xEARTH-RAISEDRAISED HERE
about 0.90x as tall as on Earth · a 5 ft 10 in adult could stand nearer 5 ft 3 in

A little heavier than home, at 1.7 times Earth's gravity. A child raised here would likely grow a little shorter and sturdier than their Earth-raised parents, about 0.90x as tall as on Earth: a 5 ft 10 in adult could stand nearer 5 ft 3 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 high and thin, almost cartoonish.

Assuming Earth-like air at this world's temperature of about 423°C (794°F), sound would travel roughly 55% 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.

Cosmic travel advisory
★★☆☆☆
Reconsider travel
  • !Blistering at about 423°C (794°F), far too hot for liquid water on the surface.
  • !Noticeably heavy, 1.7 times Earth's gravity.
  • !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
