![]() Jovian planet cores are also expected to consist of rock, metal and hydrogen. The Jovian planets’ colors differ due to their temperature, composition, and cloud height. ![]() If it could be placed in a giant swimming pool, the planet would float. Saturn, for example, is made of materials lighter than water. Jovian planets also have gaseous atmospheres, with the main gases being hydrogen and helium. Despite their size, the Jovian planets have low densities because of their gaseous composition. Jovian planets are larger, further from the sun, rotate faster, have more moons, have more rings, are less dense overall and have denser cores than terrestrial planets. Bigger & more massive Lower density, different composition All have rings All have many moons. They are opposite to terrestrial planets in many ways. Jovian Planets - Different than Terrestrial Planets. Jupiter is the densest, and the densities of the other planets increase in order of distance from the Sun. On Earth, both hydrogen and helium are gases, so Jupiter and Saturn are sometimes called gas planets. Why Are the Inner and Outer Planets Different 1. There is no clear trend in the densities. The two largest planets, Jupiter and Saturn, have nearly the same chemical makeup as the Sun they are composed primarily of the two elements hydrogen and helium, with 75 of their mass being hydrogen and 25 helium. The reason comes from the fact that it is composed of lighter. The terrestrial planets have a smaller mass because they are smaller and the Jovian planets have a higher mass because they are larger. It has (like all the Jovian planets), a low density. The internal conditions in the jovian planets are similar enough so that composition has a major effect on average density. Jovian Planets: The jovian planets, so named because of their resemblance to Jupiter, are composed of the rest of the planets in the solar system (except Pluto), so Jupiter, Saturn, Neptune and Uranus. It has a mass 318 times that of the earth. ![]() The cores of of terrestrial planets are mainly dense iron with silicate, and although jovian planets have denser cores, terrestrial planets overall are more dense. The main atmosphere of terrestrial planets is a gaseous mix of carbon dioxide and nitrogen gases, and all terrestrial planets have rocky surfaces. In addition, terrestrial planets rotate slower, lack rings and have less moons. Terrestrial Planets: Coming from the Latin word " terra", meaning "land," the terrestrial planets are Mercury, Venus, Earth and Mars.Īll the terrestrial planets are closer to the sun then the jovial planets, and the terrestrial planets are also all smaller. ![]()
