Water has a greater density than only the planet Saturn. All of the planets in the solar system have a density that is superior to that of Saturn. Saturn is one of the gas giants, made largely of hydrogen, and the second largest planet in the solar system.
Saturn is close to 800 times larger than Earth, making it the most dense of all planets. Only the planet Jupiter has a greater mass than Saturn. Jupiter has the second lowest density in the solar system, and has the same composition, hydrogen and helium, as the least dense planet. The large degree of gas composition of Saturn and Jupiter is responsible for the low densities.Learn More
Mars has a mean density of 3,933 kilograms per cubic meter, or 3.94 grams per cubic centimeter, according to NASA. By contrast, Earth has an average density of 5.51 grams per cubic centimeter. Mars is therefore only around 71 percent as dense as Earth.Full Answer >
The density of Pluto is 2.050 grams per cubic meter. This makes this dwarf planet a little more than a third as dense as Earth.Full Answer >
The density of Jupiter is 1.33 grams per cubic centimeter, making it 0.24 times as dense as Earth. It is the second-most dense of the gas giants.Full Answer >
Saturn formed according to one of two models: the core accretion model, which states that planets formed over time through gravitational forces drawing materials together, or the disk instability model, which states that clumps of dust and gas fused together quickly and progressively formed a planet.Full Answer >
