The planet Jupiter has a mean radius measurement of approximately 44,440.7 miles. However, the rotational speed of the planet causes it to bulge outwards at the equator, giving it an equatorial diameter of 88,846 miles. By comparison, at its poles, Jupiter's diameter is approximately 83,082 miles.
Unlike Earth, Jupiter is made up of gas, giving it a uniform surface that lacks high and low points, such as valleys or mountains. In volume, Jupiter is 1,321 times larger than Earth, as the surface area of Jupiter is approximately 23,713,907,537 square miles. This gives it a surface area 120 times that of Earth.
