HD 86065 b
HD 86065 b is a confirmed gas-giant exoplanet 132 ly from Earth in the constellation Hydra, discovered in 2022 by Multiple Observatories.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
HD 86065 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 0.05× as wide as ours, bathing the cloud tops in amber-orange light. A year here lasts 70.6 Earth years, and at an estimated -221°C (-365°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 18.4 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; this is the sound at the cloud tops, where the air is mostly hydrogen and helium, the lightest gases there are. Sound races through them at about 516 metres per second, 1.5 times its Earth speed, flipping a voice into a thin, cartoon-helium squeak. The temperature behind that number is this world's computed equilibrium temperature; its real atmosphere is unknown.

- !Cryogenic at roughly -221°C (-365°F), cold enough to freeze most gases solid.
- !There is nowhere to land: no ground, no deck, only cloud that thickens into crushing pressure.
- !Earth-similarity index 0.11: this world has almost nothing in common with our own.
