TOI-2084 b

TOI-2084 b is a confirmed sub-Neptune exoplanet 374 ly from Earth in the constellation Draco, discovered in 2023 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-2084 b, you would weigh roughly about 9% more than you do on Earth. Its red dwarf looks 9.5× wider than ours, bathing the surface in deep 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 6.1 days, and at an estimated 254°C (489°F) it is blistering.

much like Earth height

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 high and thin, almost cartoonish.

Assuming Earth-like air at this world's temperature of about 254°C (489°F), sound would travel roughly 35% 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
★★★☆☆
For seasoned travelers
  • !Blistering at about 254°C (489°F), far too hot for liquid water on the surface.
  • Surface gravity is close to Earth's, about 1.09 times, so you would move much as you do here.
  • !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
