2MASS J22362452+4751425 b
2MASS J22362452+4751425 b is a confirmed gas-giant exoplanet 227 ly from Earth in the constellation Lacerta, discovered in 2016 by W. M. Keck Observatory.
Imaging: photographed directly, as a faint point of light beside its star.
2MASS J22362452+4751425 b is a giant ball of gas with no solid surface to stand on; you would simply sink into ever-thicker cloud. Its orange dwarf looks 0.00× as wide as ours, bathing the cloud tops in amber-orange light. At an estimated -263°C (-441°F) it is colder than almost anywhere in the solar system.

If your children grew up herea playful thought experiment
There is no ground here to grow up on, only bottomless sky. A child could never stand, walk, or even fall to a surface, because there isn't one. Under 26.3 times Earth's gravity and pressure that only climbs the deeper you go, anything built for this world would not look human at all: picture something closer to a deep-sea creature than a person, broad and buoyant, drifting through the cloud decks with no need for legs and no floor to land on.
- Body plan
- Floating, not upright
- With no surface and no fixed up or down, a skeleton built for standing would be useless; a drifting, gas-filled body would not.
- Build
- Broad and pressure-hardened
- Pressure rises without limit toward the interior, so anything alive would have to be built like a deep-sea animal, not a land one.
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 a thin, helium-fast squeak.
There is no surface to stand on, and we have no temperature for this world, so its cloud-top acoustics cannot be modelled. In hydrogen-helium air sound races, so a voice would leap to a thin, almost cartoonish squeak.
- !There is nowhere to land: no ground, no deck, only cloud that thickens into crushing pressure.
- !Earth-similarity index 0.01: this world has almost nothing in common with our own.
