GJ 4274 c
GJ 4274 c is a confirmed sub-Neptune exoplanet 23.6 ly from Earth in the constellation Aquarius, discovered in 2026 by Mauna Kea Observatory.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
Standing on GJ 4274 c, you would weigh roughly about 5% more than you do on Earth. Its red dwarf looks about the same size as ours, bathing the surface in deep orange light. A year passes in just 70 days, and at an estimated -116°C (-176°F) it is deeply frozen.

If your children grew up herea playful thought experiment
Gravity close to Earth's, at about 1.0 times. A child would grow up much as they would back home.
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 deeper and fuller.
Assuming Earth-like air at this world's temperature of about -116°C (-176°F), sound would travel roughly 26% slower than on Earth, so your voice would sound deeper and fuller. The real atmosphere is unknown, so this is a best guess.
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.
- !Deeply frozen at around -116°C (-176°F), far below the freezing point of water.
- Surface gravity is close to Earth's, at least 1.05 times, so you would move much as you do here.

What is the gravity on GJ 4274 c?
GJ 4274 c's surface gravity is at least 1.0 times Earth's, and possibly more: its mass is only a lower bound.
How much would you weigh on GJ 4274 c?
Someone who weighs 150 pounds on Earth would weigh at least 157 pounds on GJ 4274 c.
How far is GJ 4274 c from Earth?
GJ 4274 c lies about 23.6 light-years from Earth.
How long would it take to get to GJ 4274 c?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 36,806 years.
How hot is GJ 4274 c?
GJ 4274 c's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about -116°C (-176°F).
How long is a year on GJ 4274 c?
GJ 4274 c completes one orbit of its star in 70 days.
