Jupiter’s surface gravity is 2.4 times that of the Earth’s gravity. The gravity on Jupiter is greater due to its composition of mainly gases. A man who weighs 200 pounds on Earth would weigh 480 pounds on Jupiter.
Jupiter is one of the giant gas planets, and it is the biggest planet in the solar system. It has wind speeds greater than 400 miles per hour. Another notable characteristic of this planet is the great red spot, which is actually a fierce and massive storm that is over 300 years old.
Due to the fast spin about its axis, Jupiter’s period of rotation is about 10 hours. Jupiter has 62 identified moons, of which Ganymede is the largest. It also has three thin rings.
