Jupiter's radius is about 1/10 the radius of the Sun, and its mass is 0.001 times the mass of the Sun. Jupiter's mass is 2.5 times that of all the other planets in the Solar System combined—this is so massive that its barycenter with the Sun lies above the Sun's surface at 1.068 solar radii from the Sun's center.
