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 454°C (849°F), sound would travel roughly 59% 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.

  • !Furnace-hot at around 454°C (849°F), with no liquid water and no shade anywhere.
  • Surface gravity is close to Earth's, about 1.13 times, so you would move much as you do here.
