Here is some really good information that I found at https://www.smartconversion.com/otherInfo/gravity_of_planets_and_the_sun.aspx. They have LOTS of really cool information about all the planets in the solar system. According to EnchantedLearning, the acceleration of gravity on each of the planets is:

: 38% of Earth’s
: 91% of Earth’s
: 100% of Earth’s (9.81 meters/second2)
: 38% of Earth’s
: 254% of Earth’s
: 108% of Earth’s
: 91% of Earth’s
: 119% of Earth’s
: 8% of Earth’s

So what this all means is that a person who weighs 100 pounds on Earth would weigh 38 pounds on Mercury or Mars, 91 pounds on Venus, 254 pounds on Jupiter (!!!), 108 pounds on Saturn, 91 pounds on Uranus, 119 pounds on Neptune, or only 8 pounds on Pluto.

Check out the above links to find out more information about each planet, including a bit of an explanation for why each planet’s gravity is what it is.
