HD 190360 d
HD 190360 d is a confirmed sub-Neptune exoplanet 52.2 ly from Earth in the constellation Cygnus, discovered in 2026 by Multiple Facilities.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
Standing on HD 190360 d, you would weigh almost exactly what you weigh on Earth. Its yellow, Sun-like star looks 2.9× wider than ours, bathing the surface in warm white light. A year passes in just 89 days, and at an estimated 186°C (367°F) it is blistering.

If your children grew up herea playful thought experiment
Gravity close to Earth's, at 0.98 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 186°C (367°F), sound would travel roughly 26% 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.

- !Blistering at about 186°C (367°F), far too hot for liquid water on the surface.
- Surface gravity is close to Earth's, 0.98 times, so you would move much as you do here.
