Planet Saturn
Saturn is the six planet from the sun in our Solar System. It is the second largest Planet. Saturn appears to be similar to Jupiter in many ways. Saturn is the least dense of all the planets. Its density of 704kg m-3 is less than that of water so that one might imagine Saturn being placed in a tank of water and floating! Like Jupiter, Saturn must be composed predominantly of hydrogen and helium.
Saturn’s mass is 95.147 times that of the Earth. The equatorial radius is 60,000 km. The polar radius is 11% smaller, making Saturn by far the most flattened planet. The average density of704 kgm-3 follows from these figures; this is about half the average density of Jupiter & one-eight that of the Earth.
