What would you weigh on Kepler-431 b?
Kepler-431 b’s surface gravity is 0.63× Earth’s, so you would weigh about 37% less than you weigh on Earth. That gravity is an estimate: the mass behind it is derived from this world's size. Kepler-431 b’s gravity is stronger than 5% of the known worlds in gravityfinder (a low bar to miss: most confirmed exoplanets are giants far heavier than Earth).
On Kepler-431 b you would weigh
≈ 95.1 lb
For scale: the gentlest gravity of any world here is Charon at 0.03×, and the most crushing is Kepler-123 b at 6.40×.
Surface gravity computed by gravityfinder from Kepler-431 b’s mass and radius (gravity = mass ÷ radius², with Earth = 1). Mass estimated from size.
