TOI-561 e
TOI-561 e is a confirmed sub-Neptune exoplanet 280 ly from Earth in the constellation Sextans, 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 TOI-561 e, you would weigh about 96% more than you do on Earth. Its yellow, Sun-like star looks 2.6× wider than ours, bathing the surface in warm white light. A year passes in just 77 days, and at an estimated 143°C (289°F) it is blistering.

If your children grew up herea playful thought experiment
Heavier than home, at 2.0 times Earth's gravity. A child would end up markedly shorter and powerfully built, about 0.87x as tall as on Earth: a 5 ft 10 in adult could stand nearer 5 ft 1 in. Bones, muscle, and heart would all grow heavier just to stand and move.
- Bones
- Thick and dense
- More weight to bear forces the skeleton to grow denser and stronger all through childhood.
- Heart
- Large and powerful
- Pushing blood upward against stronger gravity demands a bigger, harder-working heart.
- Movement
- Low and deliberate
- A fall under this gravity lands hard, so movement stays slow, planted, and careful.
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 noticeably higher and reedier.
Assuming Earth-like air at this world's temperature of about 143°C (289°F), sound would travel roughly 20% faster than on Earth, so your voice would sound noticeably higher and reedier. The real atmosphere is unknown, so this is a best guess.

- !Persistently hot at around 143°C (289°F), well above anything you would call comfortable.
- !Noticeably heavy, 2.0 times Earth's gravity.
