largest planet

Jupiter is both the largest planet in the solar system and the most massive. Its equatorial diameter is 143,884 km, which is 11.209 times the diameter of Earth, and 0.103 times the diameter of the Sun. Jupiter is not spherical because it spins rapidly and is made of gas and liquid. Its polar diameter is 133,708 km. The volume of Jupiter is equivalent to 1319 Earths. Jupiter's mass is 318 times Earth's mass, which is 2.5 times greater than total mass of all the other planets. It would take 1047 Jupiters to make up the mass of the Sun. The equatorial diameter of the next largest planet, Saturn, is 0.84 that of Jupiter and its mass is 0.30 Jupiter's. Both Jupiter and Saturn grew into relatively large planets because they formed at a place and time in the early development of the solar system that enabled them to collect vast quantities of gas from the solar nebula.
