LP 261-75 b
LP 261-75 b is a confirmed gas-giant exoplanet 111 ly from Earth in the constellation Leo Minor, discovered in 2006 by Apache Point Observatory.
Imaging: photographed directly, as a faint point of light beside its star.
LP 261-75 b is a giant ball of gas with no solid surface to stand on; you would simply sink into ever-thicker cloud. Its red dwarf looks 0.00× as wide as ours, bathing the cloud tops in dim red light. At an estimated 1227°C (2240°F) it is hot enough to melt rock.
Catalog values (NASA Exoplanet Archive): mass 6,674 M⊕, radius 12.10 R⊕. Its catalog mass and radius imply a density of 20.8 g/cm³, denser than compressed iron, so they cannot both be right, and gravityfinder does not use LP 261-75 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 2,755 metres per second, 8.1 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.
- !At about 1227°C (2240°F), the daytime side glows: metals run liquid and any atmosphere is being torn away.
- !There is nowhere to land: no ground, no deck, only cloud that thickens into crushing pressure.
- !Earth-similarity index 0.07: this world has almost nothing in common with our own.
