What would you weigh on WASP-123 b?

Q: What would you weigh on WASP-123 b?

WASP-123 b has no solid surface. At its cloud tops gravity pulls 1.25 times as hard as Earth's, so a 150 lb person would weigh about 187 lb there.

WASP-123 b’s surface gravity is 1.25× Earth’s, so you would weigh about 25% more than you weigh on Earth.

EXCLUDEDCALCULATEDWASP-123 b has no solid surface, so its gravity is the pull at the cloud tops, and it is excluded from surface-gravity rankings.
