K2-198 c
K2-198 c is a confirmed rocky exoplanet 361 ly from Earth in the constellation Virgo, discovered in 2019 by K2.
Transit: spotted by the tiny, repeating dip in its star’s light each time the planet crosses in front of it.
Standing on K2-198 c, you would weigh roughly about 29% more than you do on Earth. Bathing the surface in warm white light. A year passes in just 3.4 days, and at an estimated 957°C (1754°F) it is hot enough to melt rock.

If your children grew up herea playful thought experiment
Gravity close to Earth's, at about 1.3 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 957°C (1754°F), sound would travel roughly 107% 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 957°C (1754°F), the daytime side glows: metals run liquid and any atmosphere is being torn away.
- Surface gravity is close to Earth's, about 1.29 times, so you would move much as you do here.
