What would you weigh on KELT-9 b?

Q: What would you weigh on KELT-9 b?

KELT-9 b has no solid surface. At its cloud tops gravity pulls 1.94 times as hard as Earth's, so a 150 lb person would weigh about 292 lb there.

KELT-9 b’s surface gravity is 1.94× Earth’s, so you would weigh about 94% more than you weigh on Earth.

EXCLUDEDCALCULATEDKELT-9 b has no solid surface, so its gravity is the pull at the cloud tops, and it is excluded from surface-gravity rankings.
