OGLE-2005-BLG-390L b
OGLE-2005-BLG-390L b is a confirmed sub-Neptune exoplanet 21,526 ly from Earth in the constellation Scorpius, discovered in 2005 by OGLE.
Microlensing: spotted when its gravity briefly magnified the light of a more distant star.
Standing on OGLE-2005-BLG-390L b, you would weigh about 13% more than you do on Earth. A year here lasts 9.0 Earth years, and at an estimated -223°C (-370°F) it is colder than almost anywhere in the solar system.

If your children grew up herea playful thought experiment
Gravity close to Earth's, at 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 deep and slow, dropped to a low bass.
Assuming Earth-like air at this world's temperature of about -223°C (-370°F), sound would travel roughly 58% slower than on Earth, so your voice would sound deep and slow, dropped to a low bass. The real atmosphere is unknown, so this is a best guess.

- !Cryogenic at roughly -223°C (-370°F), cold enough to freeze most gases solid.
- Surface gravity is close to Earth's, 1.13 times, so you would move much as you do here.
- !Earth-similarity index 0.17: this world has almost nothing in common with our own.
