What would you weigh on GJ 238 b?

Q: What would you weigh on GJ 238 b?

GJ 238 b has a surface gravity 0.39 times Earth's, so you would weigh about 61% less than you weigh on Earth. A 150 lb person would weigh about 59 lb there.

GJ 238 b’s surface gravity is 0.39× Earth’s, so you would weigh about 61% less than you weigh on Earth. That gravity is an estimate: the mass behind it is derived from this world's size. GJ 238 b’s gravity is stronger than 2% of the known worlds in gravityfinder (a low bar to miss: most confirmed exoplanets are giants far heavier than Earth).

World	Gravity	You’d weigh
The Moon	0.17×	24.8 lb
Mars	0.38×	56.7 lb
GJ 238 b	0.39×	≈ 59 lb
Earth	1.00×	150 lb
