HD 136352 c
HD 136352 c is a confirmed sub-Neptune exoplanet 47.9 ly from Earth in the constellation Lupus, discovered in 2019 by La Silla Observatory.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
Standing on HD 136352 c, you would weigh about 32% more than you do on Earth. Its yellow, Sun-like star looks 6.1× wider than ours, bathing the surface in warm 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 28 days, and at an estimated 404°C (759°F) it is blistering.

If your children grew up herea playful thought experiment
A little heavier than home, at 1.3 times Earth's gravity. A child raised here would likely grow a little shorter and sturdier than their Earth-raised parents, about 0.95x as tall as on Earth: a 5 ft 10 in adult could stand nearer 5 ft 6 in, with denser bones.
- Bones
- Thick and dense
- More weight to bear forces the skeleton to grow denser and stronger all through childhood.
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 404°C (759°F), sound would travel roughly 53% 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 404°C (759°F), far too hot for liquid water on the surface.
- Surface gravity is close to Earth's, 1.32 times, so you would move much as you do here.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
