TOI-1782.02

TOI-1782.02 is a confirmed sub-Neptune exoplanet 311 ly from Earth in the constellation Ursa Minor, 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-1782.02, you would weigh roughly about 19% more than you do on Earth. Its orange dwarf looks 25.9× wider than ours, bathing the surface in amber-orange 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 1.8 days, and at an estimated 702°C (1295°F) it is furnace-hot.

Gravity close to Earth's, at about 1.2 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.

Your voice would sound high and thin, almost cartoonish.

Assuming Earth-like air at this world's temperature of about 702°C (1295°F), sound would travel roughly 84% 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
  • !Furnace-hot at around 702°C (1295°F), with no liquid water and no shade anywhere.
  • Surface gravity is close to Earth's, about 1.19 times, so you would move much as you do here.
  • !Its star delivers about 214 times the sunlight Earth gets, a blinding, sterilizing glare.
  • !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
