What would you weigh on Kepler-81 c?

Kepler-81 c’s surface gravity is 0.77× Earth’s, so you would weigh about 23% less than you weigh on Earth. That gravity comes from a measured mass. Kepler-81 c’s gravity is stronger than 10% of the known worlds in gravityfinder (a low bar to miss: most confirmed exoplanets are giants far heavier than Earth).

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-81 c’s mass and radius (gravity = mass ÷ radius², with Earth = 1). Measured mass.
