HD 48948 d
HD 48948 d is a confirmed sub-Neptune exoplanet 55.1 ly from Earth in the constellation Lynx, discovered in 2024 by Roque de los Muchachos Observatory.
Radial Velocity: spotted by the gravitational wobble the planet tugs in its star.
Standing on HD 48948 d, you would weigh roughly almost exactly what you weigh on Earth. Its orange dwarf looks 1.4× wider than ours, bathing the surface in amber-orange light. A year passes in just 152 days, and at an estimated 76°C (169°F) it is warm.

If your children grew up herea playful thought experiment
Gravity close to Earth's, at about 1.0 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 noticeably higher and reedier.
Assuming Earth-like air at this world's temperature of about 76°C (169°F), sound would travel roughly 10% 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 76°C (169°F), well above anything you would call comfortable.
- Surface gravity is close to Earth's, at least 1.01 times, so you would move much as you do here.
