Here is some really good information that I found at EnchantedLearning.com.
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:
Mercury: 38% of Earth’s
Venus: 91% of Earth’s
Earth: 100% of Earth’s (9.81 meters/second2)
Mars: 38% of Earth’s
Jupiter: 254% of Earth’s
Saturn: 108% of Earth’s
Uranus: 91% of Earth’s
Neptune: 119% of Earth’s
Pluto: 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.
