Surface area of Jupiter,[91] the "surface" area of the spheroid (calculated from the mean radius as reported by NASA). The cross-sectional area of Jupiter, which is the same as the "circle" of Jupiter seen by an approaching spacecraft, is almost exactly one quarter the surface-area of the overall sphere, which in the case of Jupiter is approximately 1.535×1016 m2.
