Which planet weighs over twice as much as all the other known planets combined?
Answer: Jupiter is the fifth planet from the Sun and the largest planet in the Solar System. It is two and a half times the mass of all the other planets in the Solar System combined. With a radius of 43,440.7 miles, Jupiter is 11 times wider than Earth. If Earth were the size of a nickel, Jupiter would be about as big as a basketball. Its atmosphere is mostly hydrogen and helium, and its iconic Great Red Spot is a giant storm bigger than Earth that has raged for hundreds of years. More than 1,300 Earths would fit inside Jupiter.
Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a giant planet with a mass one-thousandth that of the Sun, but two and a half times that of all the other planets in the Solar System combined.
