Jupiter has an equatorial diameter of about 88,846 miles (142,984 kilometers), which is roughly 11 times the diameter of Earth. Its polar diameter is slightly smaller at about 83,082 miles (133,708 kilometers) due to its oblate spheroid shape caused by rapid rotation
. The mean radius of Jupiter is approximately 43,440.7 miles (69,911 kilometers)
. In terms of volume, Jupiter is about 1,321 times larger than Earth, meaning over 1,300 Earths could fit inside it
. Its surface area is about 23.7 billion square miles (6.14 x 10^10 square kilometers), which is about 120 times that of Earth
. Thus, Jupiter is the largest planet in the solar system by a significant margin, with a size about 11 times that of Earth in diameter and over a thousand times in volume
