Science Factoid - 1

Did you know that the gravity on Saturn is less than the gravity on Earth? Weird, huh, but it's because gravity is defined as the gravitational force on the surface of the planet. Saturn is ten times more massive than Earth, it is also one-tenth the density while being ten times bigger in diameter.  So the math works out that Saturn's gravity is 9 m/s2 vs Earth's 9.8 m/s2
