LHS 475 b
LHS 475 b is a confirmed rocky exoplanet 40.7 ly from Earth in the constellation Octans, discovered in 2023 by Transiting Exoplanet Survey Satellite (TESS).
Transit: spotted by the tiny, repeating dip in its star’s light each time the planet crosses in front of it.
Standing on LHS 475 b, you would weigh roughly about 4% less than you do on Earth. Its red dwarf looks 13.7× 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 2.0 days, and at an estimated 313°C (595°F) it is blistering.

If your children grew up herea playful thought experiment
Gravity close to Earth's, at about 0.96 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 high and thin, almost cartoonish.
Assuming Earth-like air at this world's temperature of about 313°C (595°F), sound would travel roughly 43% 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.

- !Blistering at about 313°C (595°F), far too hot for liquid water on the surface.
- Surface gravity is close to Earth's, about 0.96 times, so you would move much as you do here.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
