What would you weigh on HD 141399 b?
HD 141399 b’s surface gravity is 0.70× Earth’s, so you would weigh about 30% 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 141399 b’s gravity is stronger than 7% of the known worlds in gravityfinder (a low bar to miss: most confirmed exoplanets are giants far heavier than Earth).
On HD 141399 b you would weigh
≈ 105 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 HD 141399 b’s mass and radius (gravity = mass ÷ radius², with Earth = 1). Minimum mass only.
