TOI-4633 c
TOI-4633 c is a confirmed sub-Neptune exoplanet 311 ly from Earth in the constellation Draco, 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.
Standing on TOI-4633 c, you would weigh about 1101% more than you do on Earth. Its yellow, Sun-like star looks 1.2× wider than ours, bathing the surface in warm white light. A year passes in just 272 days, and at an estimated -5°C (24°F) it is cold.

If your children grew up herea playful thought experiment
Beyond about four times Earth's gravity, a growing child's skeleton could not carry its own weight. A human body simply could not develop here, even sheltered indoors. The shape below is only where the trend points before biology gives out: short, and impossibly dense.
- Bones
- Thick and dense
- More weight to bear forces the skeleton to grow denser and stronger all through childhood.
- Heart
- Large and powerful
- Pushing blood upward against stronger gravity demands a bigger, harder-working heart.
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 much as it does on Earth.
Assuming Earth-like air at this world's temperature of about -5°C (24°F), sound would travel close to its Earth speed, so your voice would sound much as it does on Earth. The real atmosphere is unknown.
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.
- Surface temperatures near -5°C (24°F) fall in the range where liquid water is at least possible.
- !Gravity is 12.0 times Earth's, near the limit at which a person can stand or walk at all.

What is the gravity on TOI-4633 c?
TOI-4633 c's surface gravity is about 12 times Earth's.
How much would you weigh on TOI-4633 c?
Someone who weighs 150 pounds on Earth would weigh about 1,802 pounds on TOI-4633 c.
How far is TOI-4633 c from Earth?
TOI-4633 c lies about 311 light-years from Earth.
How long would it take to get to TOI-4633 c?
At the speed of NASA's Parker Solar Probe, the fastest craft ever built, the journey would take about 484,268 years.
How hot is TOI-4633 c?
TOI-4633 c's equilibrium temperature, the balance it reaches from its star's light alone before any greenhouse warming, is about -5°C (24°F).
Is TOI-4633 c habitable?
TOI-4633 c orbits near its star's habitable zone, the range of distances where liquid water could be stable, and its Earth-similarity index is 0.61. 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 TOI-4633 c?
TOI-4633 c completes one orbit of its star in 272 days.
