What planet would we weigh the same as we do now on

The closest one in our solar system is Venus.
The acceleration of gravity on Venus is 8.87 m/s², compared to our 9.81 m/s².
So the gravity on the surface of Venus is 90.4% of what we're used to.
If you weigh 150 pounds on Earth, you'd weigh about 136 pounds on Venus.

This doesn't mean that you would be comfortable on the surface of Venus,
since the average temperature there is something like 860° !


Oh !  Now I see that the choices are Mars, Mercury, or Jupiter.

Planet         Gravity     % of Earth gravity     Weight of 150-lb person

Mercury        3.73            38.0%                        57.0 lbs
Mars             3.71            37.8%                        56.7 lbs
Jupiter        24.79           252.7%                       379  lbs

None of these 3 planets is anywhere close to Earth gravity.
Mercury and Mars are almost tied, with Mercury slightly closer.
