Jupiter has the largest atmosphere
Saturn has the lowest density
The four Jovian planets
No. Terrestrial planets are much denser than Jovian planets.
Saturn is the least dense out of all of the planets in our solar system. Its average density is around 0.7 g/cc (less than water). It also has a thick Hydrogen/Helium atmosphere.
The Earth has the greatest average density, of all the planets.
The average density of the terrestrial planets is greater than the density of Earth's crust. Terrestrial planets have higher densities due to their composition of rock and metal, while Earth's crust is composed of lighter minerals like granite and basalt.
The average density of Jovian (gas giant) planets like Jupiter and Saturn is low compared to terrestrial planets like Earth. Their densities are around 1-2 grams per cubic centimeter due to being primarily composed of hydrogen and helium gases with small rocky cores.
No, size does not go with density. The Earth is the most dense planet in the solar system, but it is the 4th smallest planet.
Mars is the least dense of the rocky planets.
Mercury is the smallest of the four inner planets and closest to the sun. It is also the smallest of all eight planets.
The density of a planet depends basically on the density of the materials that make the planet up. It is a weighted average of those densities.
Because the outer planets are composed of mainly gas or ice, whereas the inner planets are composed of rock which has a higher density.
Neptune has the largest orbital radius among the eight planets in our solar system. Its average distance from the Sun is about 4.5 billion kilometers.
