LHS 1903 e
LHS 1903 e is a confirmed sub-Neptune exoplanet 116 ly from Earth in the constellation Lynx, discovered in 2026 by CHaracterising ExOPlanets Satellite (CHEOPS).
Transit: spotted by the tiny, repeating dip in its star’s light each time the planet crosses in front of it.
Standing on LHS 1903 e, you would weigh about 93% more than you do on Earth. Its red dwarf looks 3.6× 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 29 days, and at an estimated 60°C (140°F) it is warm.

If your children grew up herea playful thought experiment
Heavier than home, at 1.9 times Earth's gravity. A child would end up markedly shorter and powerfully built, about 0.88x 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 much as it does on Earth.
Assuming Earth-like air at this world's temperature of about 60°C (140°F), sound would travel roughly 8% faster than on Earth, so your voice would sound much as it does on Earth. The real atmosphere is unknown, so this is a best guess.
A real voice sample, pitch-shifted (tempo held constant) to suggest the acoustics: a playful approximation, not a precise simulation. Voice: Lingua Libre / Vealhurl, CC BY-SA 4.0.
- !Persistently hot at around 60°C (140°F), well above anything you would call comfortable.
- !Noticeably heavy, 1.9 times Earth's gravity.
- !Likely tidally locked: one hemisphere in endless day, the other in permanent night.
