TOI-1203 c
TOI-1203 c is a confirmed sub-Neptune exoplanet 212 ly from Earth in the constellation Hydra, discovered in 2025 by La Silla Observatory.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
Standing on TOI-1203 c, you would weigh roughly about 13% more than you do on Earth. Bathing the surface in warm white light. A year passes in just 13 days.

If your children grew up herea playful thought experiment
Gravity close to Earth's, at about 1.1 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 much as it does on Earth.
We do not yet have a temperature for this world, and its atmosphere is unknown, so its acoustics cannot be modelled. In Earth-like air a human voice carries as you know it, and without the temperature that is as far as the physics will take us.
- Surface gravity is close to Earth's, at least 1.13 times, so you would move much as you do here.
