KMT-2017-BLG-1003L b
KMT-2017-BLG-1003L b is a confirmed sub-Neptune exoplanet 23,124 ly from Earth in the constellation Ophiuchus, discovered in 2023 by KMTNet.
Microlensing: spotted when its gravity briefly magnified the light of a more distant star.
Standing on KMT-2017-BLG-1003L b, you would weigh about 14% more than you do on Earth.
What these mean: surface gravity · tidal locking · equilibrium temperature
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 much as it does on Earth.
We do not yet have a temperature for this world, and its atmosphere is unknown, so its acoustics cannot be modelled. In Earth-like air a human voice carries as you know it, and without the temperature that is as far as the physics will take us.
- Surface gravity is close to Earth's, 1.14 times, so you would move much as you do here.
