HIP 116454 b
HIP 116454 b is a confirmed sub-Neptune exoplanet 204 ly from Earth in the constellation Pisces, discovered in 2014 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 HIP 116454 b, you would weigh about 59% more than you do on Earth. Its orange dwarf looks 9.6× wider than ours, bathing the surface in amber-orange 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 9.1 days, and at an estimated 480°C (896°F) it is furnace-hot.

If your children grew up herea playful thought experiment
A little heavier than home, at 1.6 times Earth's gravity. A child raised here would likely grow a little shorter and sturdier than their Earth-raised parents, about 0.91x as tall as on Earth: a 5 ft 10 in adult could stand nearer 5 ft 4 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 480°C (896°F), sound would travel roughly 62% 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 480°C (896°F), with no liquid water and no shade anywhere.
- !Noticeably heavy, 1.6 times Earth's gravity.
- !Its star delivers about 51 times the sunlight Earth gets, a blinding, sterilizing glare.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
