TOI-913 b
TOI-913 b is a confirmed sub-Neptune exoplanet 213 ly from Earth in the constellation Apus, 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 TOI-913 b, you would weigh roughly about 10% more than you do on Earth. Bathing the surface in amber-orange light. A year passes in just 11 days, and at an estimated 439°C (822°F) it is furnace-hot.

If your children grew up herea playful thought experiment
Gravity close to Earth's, at about 1.1 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 439°C (822°F), sound would travel roughly 57% 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 439°C (822°F), with no liquid water and no shade anywhere.
- Surface gravity is close to Earth's, about 1.10 times, so you would move much as you do here.
- !Its star delivers about 110 times the sunlight Earth gets, a blinding, sterilizing glare.
