V830 Tau b
V830 Tau b is a confirmed gas-giant exoplanet 424 ly from Earth in the constellation Taurus, discovered in 2016 by Multiple Observatories.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
V830 Tau 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 34.8× wider than ours, bathing the cloud tops in amber-orange light. A year passes in just 4.9 days, and at an estimated 941°C (1725°F) it is hot enough to melt rock.

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 1.1 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 2,479 metres per second, 7.3 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 941°C (1725°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 370 times the sunlight Earth gets, a blinding, sterilizing glare.
- !Earth-similarity index 0.09: this world has almost nothing in common with our own.

What is the gravity on V830 Tau b?
V830 Tau b is a gas giant with no solid surface to stand on. At its cloud tops, gravity pulls about 1.1 times as hard as Earth's.
How far is V830 Tau b from Earth?
V830 Tau b lies about 424 light-years from Earth.
How long would it take to get to V830 Tau b?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 661,843 years.
How hot is V830 Tau b?
V830 Tau b's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about 941°C (1725°F).
How long is a year on V830 Tau b?
V830 Tau b completes one orbit of its star in 4.9 days.
