HD 108236 c

HD 108236 c is a confirmed sub-Neptune exoplanet 211 ly from Earth in the constellation Centaurus, discovered in 2020 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 HD 108236 c, you would weigh roughly about 15% more than you do on Earth. Its yellow, Sun-like star looks 14.1× 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 6.2 days, and at an estimated 659°C (1218°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.

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 659°C (1218°F), sound would travel roughly 80% 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 659°C (1218°F), with no liquid water and no shade anywhere.
  • Surface gravity is close to Earth's, about 1.15 times, so you would move much as you do here.
  • !Its star delivers about 162 times the sunlight Earth gets, a blinding, sterilizing glare.
  • !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
