TIC 4672985 b

TIC 4672985 b is a confirmed gas-giant exoplanet 826 ly from Earth in the constellation Cetus, discovered in 2024 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.

TIC 4672985 b is a giant ball of gas with no solid surface to stand on; you would simply sink into ever-thicker cloud. Its yellow, Sun-like star looks 3.5× wider than ours, bathing the cloud tops in warm white light. A year passes in just 69 days, and at an estimated 244°C (471°F) it is blistering.

If your children grew up herea playful thought experiment
NO GROUND: A DRIFTER, NOT A WALKER

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 30.6 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 1,618 metres per second, 4.8 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.

sound speed ≈ 1618 m/s · 4.76× Earth

The journey
Cosmic travel advisory
☆☆☆☆
Do not travel
  • !Blistering at about 244°C (471°F), far too hot for liquid water on the surface.
  • !There is nowhere to land: no ground, no deck, only cloud that thickens into crushing pressure.
