HD 110082 b
HD 110082 b is a confirmed sub-Neptune exoplanet 343 ly from Earth in the constellation Octans, discovered in 2021 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 HD 110082 b, you would weigh roughly almost exactly what you weigh on Earth. Its yellow-white star looks 10.5× wider than ours, bathing the surface in bright white 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 10 days, and at an estimated 684°C (1263°F) it is furnace-hot.

If your children grew up herea playful thought experiment
Gravity close to Earth's, at about 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 high and thin, almost cartoonish.
Assuming Earth-like air at this world's temperature of about 684°C (1263°F), sound would travel roughly 82% 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.

- !Furnace-hot at around 684°C (1263°F), with no liquid water and no shade anywhere.
- Surface gravity is close to Earth's, about 1.01 times, so you would move much as you do here.
- !Its star delivers about 198 times the sunlight Earth gets, a blinding, sterilizing glare.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
