AU Mic d

AU Mic d is a confirmed rocky exoplanet 31.7 ly from Earth in the constellation Microscopium, discovered in 2023 by Multiple Observatories.

Transit Timing Variations: inferred from the gravitational tug it puts on a sibling planet’s transit timing.

If your children grew up herea playful thought experiment
EARTH HEIGHT≈ 1.00xEARTH-RAISEDRAISED HERE
much like Earth height

Gravity close to Earth's, at 1.0 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 much as it does on Earth.

We do not yet have a temperature for this world, and its atmosphere is unknown, so its acoustics cannot be modelled. In Earth-like air a human voice carries as you know it, and without the temperature that is as far as the physics will take us.

Cosmic travel advisory
★★★★
Recommended, with reservations
  • Surface gravity is close to Earth's, 1.01 times, so you would move much as you do here.
