WD 1856+534 b
WD 1856+534 b is a confirmed gas-giant exoplanet 80.7 ly from Earth in the constellation Draco, discovered in 2020 by Transiting Exoplanet Survey Satellite (TESS).
Transit: spotted by the tiny, repeating dip in its star’s light each time the planet crosses in front of it (what that means).
WD 1856+534 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 0.64× as wide as ours, bathing the cloud tops in amber-orange light. A year passes in just 1.4 days, and at an estimated -110°C (-166°F) it is deeply frozen.
Catalog values (NASA Exoplanet Archive): mass 4,386 M⊕, radius 10.40 R⊕. Its catalog mass and radius imply a density of 21.5 g/cm³, denser than compressed iron, so they cannot both be right, and gravityfinder does not use WD 1856+534 b in gravity rankings or weight calculations.

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 crushing 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 demoEXPERIMENTAL · just for fun
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 908 metres per second, 2.7 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. The demo plays the shift capped at 1.8x; the real effect would be even stronger.
A real voice sample, pitch-shifted (tempo held constant) to suggest the acoustics: a playful approximation, not a precise simulation. Voice: Lingua Libre / Vealhurl, CC BY-SA 4.0.

- !There is nowhere to land: no ground, no deck, only cloud that thickens into crushing pressure.
