TOI-4602.01

TOI-4602.01 is a confirmed sub-Neptune exoplanet 206 ly from Earth in the constellation Perseus, 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-4602.01, you would weigh about 8% less than you do on Earth. Its yellow, Sun-like star looks 22.7× wider than ours, bathing the surface in warm white light. It is likely tidally locked, so that sun never moves in the sky: one hemisphere in endless day, the other in permanent night. A year passes in just 4.0 days, and at an estimated 1071°C (1960°F) it is hot enough to melt rock.

much like Earth height

Gravity close to Earth's, at 0.92 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 high and thin, almost cartoonish.

Assuming Earth-like air at this world's temperature of about 1071°C (1960°F), sound would travel roughly 116% faster than on Earth, so your voice would sound high and thin, almost cartoonish. The real atmosphere is unknown, so this is a best guess.

The journey
Cosmic travel advisory
☆☆☆☆
Do not travel
  • !At about 1071°C (1960°F), the daytime side glows: metals run liquid and any atmosphere is being torn away.
  • Surface gravity is close to Earth's, 0.92 times, so you would move much as you do here.
  • !Its star delivers about 664 times the sunlight Earth gets, a blinding, sterilizing glare.
  • !Earth-similarity index 0.16: this world has almost nothing in common with our own.
  • !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
