What would you weigh on HD 199509 b?

Q: What would you weigh on HD 199509 b?

HD 199509 b has a surface gravity 0.78 times Earth's, so you would weigh about 22% less than you weigh on Earth. A 150 lb person would weigh about 117 lb there.

HD 199509 b’s surface gravity is 0.78× Earth’s, so you would weigh about 22% less than you weigh on Earth. It is a giant planet with no solid surface, so this is the pull you would feel at its cloud tops. HD 199509 b’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).
