What would you weigh on Charon?
Charon’s surface gravity is 0.03× Earth’s, so you would weigh about 97% less than you weigh on Earth. That gravity comes from a measured mass. Charon’s gravity is stronger than 0% of the known worlds in gravityfinder (a low bar to miss: most confirmed exoplanets are giants far heavier than Earth).
On Charon you would weigh
4.4 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 Charon’s mass and radius (gravity = mass ÷ radius², with Earth = 1). Measured mass.
