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.
