TYC 4282-00605-1 b

TYC 4282-00605-1 b is a confirmed gas-giant exoplanet 1,514 ly from Earth in the constellation Cepheus, discovered in 2017 by Roque de los Muchachos Observatory.

Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.

TYC 4282-00605-1 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 38.0× wider than ours, bathing the cloud tops in amber-orange light. A year passes in just 102 days, and at an estimated 1012°C (1854°F) it is hot enough to melt rock.

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 about 22.3 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; 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 2,550 metres per second, 7.5 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. The demo plays the shift capped at 1.8x; the real effect would be even stronger.

sound speed ≈ 2550 m/s · 7.50× Earth

The journey
Cosmic travel advisory
☆☆☆☆
Do not travel
  • !At about 1012°C (1854°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.
  • !Its star delivers about 456 times the sunlight Earth gets, a blinding, sterilizing glare.
  • !Earth-similarity index 0.10: this world has almost nothing in common with our own.
