TOI-6255 b
TOI-6255 b is a confirmed rocky exoplanet 66.3 ly from Earth in the constellation Lacerta, discovered in 2024 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-6255 b, you would weigh about 24% more than you do on Earth. Bathing the surface in deep orange light. A year passes in just 5.7 hours, and at an estimated 983°C (1802°F) it is hot enough to melt rock.

If your children grew up herea playful thought experiment
Gravity close to Earth's, at 1.2 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 983°C (1802°F), sound would travel roughly 109% 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.

- !At about 983°C (1802°F), the daytime side glows: metals run liquid and any atmosphere is being torn away.
- Surface gravity is close to Earth's, 1.24 times, so you would move much as you do here.
- !Its star delivers about 589 times the sunlight Earth gets, a blinding, sterilizing glare.
