What would you weigh on HR 858 c?

Q: What would you weigh on HR 858 c?

HR 858 c has a surface gravity 0.97 times Earth's, so you would weigh about the same as you weigh on Earth. A 150 lb person would weigh about 146 lb there.

HR 858 c’s surface gravity is 0.97× Earth’s, so you would weigh about the same as you weigh on Earth. That gravity comes from a measured mass. HR 858 c’s gravity is stronger than 21% of the known worlds in gravityfinder (a low bar to miss: most confirmed exoplanets are giants far heavier than Earth).
