GJ 2056 b

GJ 2056 b is a confirmed Neptune-like exoplanet 92.8 ly from Earth in the constellation Canis Major, discovered in 2020 by Multiple Observatories.

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

GJ 2056 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 2.5× wider than ours, bathing the cloud tops in amber-orange light. A year passes in just 70 days, and at an estimated 38°C (100°F) it is warm.

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 0.9 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 1,254 metres per second, 3.7 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.

The journey
Cosmic travel advisory
☆☆☆☆
Do not travel
  • Surface temperatures near 38°C (100°F) fall in the range where liquid water is at least possible.
  • !There is nowhere to land: no ground, no deck, only cloud that thickens into crushing pressure.

Common questions

What is the gravity on GJ 2056 b?

GJ 2056 b is a gas giant with no solid surface to stand on. At its cloud tops, gravity pulls at least 0.93 times as hard as Earth's.

How far is GJ 2056 b from Earth?

GJ 2056 b lies about 92.8 light-years from Earth.

How long would it take to get to GJ 2056 b?

At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 144,685 years.

How hot is GJ 2056 b?

GJ 2056 b's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about 38°C (100°F).

Is GJ 2056 b habitable?

GJ 2056 b orbits near its star's habitable zone, the range of distances where liquid water could be stable, and its Earth-similarity index is 0.54. That makes it worth studying, but it is not evidence of life: we have no measurement of its atmosphere, water, or surface.

How long is a year on GJ 2056 b?

GJ 2056 b completes one orbit of its star in 70 days.
