The Jovian Planets Essay -- essays research papers

The Jovian Planets     Far beyond Earth in the solar nebula lies an ice belt and beyond that lay the four Jovian planets. They argon Jupiter, Saturn, Uranus and Neptune. Jovian means "Jupiter- like" in which the rest of the jovian planets do coincide with the name. Uranus Neptune and Saturn, all carry the kindred traits as Jupiter. The jovian planets atomic number 18 large spoil giants that contain mainly a thick line of Hydrogen and helium. These planets do not amaze solid surfaces, rather they unspoiled get denser with depth. They contain high mass and are normally anywhere from 15 to 318 condemnations the mass of earth. They also contain umteen satellites and the somberness is much stronger than that of earth. The jovian planets inner structure probably consists of a high-strung core of metals, water, ammonia and methane. Usually these cores are somewhat the corresponding coat as earth possibly a little larger. It is also accomplishable that Uranus and Neptunes core is a liquid instead of a solid. The Jovian planets also arrest somewhat the same rotational characteristics and all have rings around them. Jupiter, the first of the jovian planets, reigns supreme throughout the solar system. Named after the Roman god Jove, the ruler of Olympus Jupiter is the fifth planet from the sun and is also the largest planet in the Earths solar system. It is 318 times to a greater extent massive than Earth and is two thirds of the planetary mass in the solar system. Jupiters surface, unlike earth, is gaseous and not a solid. It is about 90% hydrogen and 10% helium with traces of methane, ammonia, water and rock. Jupiters inside is very similar to the Suns interior but with a far lower temperature. However, it is still unknown but Jupiter is believed to have a core of liquid metallic hydrogen. This exotic element can entirely be achieved at pressure greater than 4 million bars. Jupiter radiates more energy in space than it r eceives from the sun. The interior of Jupiter is hot and has been estimated to be 20000 degrees Kelvin. The rut is generated by the Kelvin- Hemholtz mechanism, or the gravitational compression of a planet. It gives off about 1.5 to 2 times more energy than the sun. It is speculated that the source of this heat is collectable to the rapid rotation of the planet and its liquid metallic hydrogen core.Liquid Metallic hydrogen consists mainly of ionized protons and electrons and is the electric... ... tidal forces, which caused nitro gas volcanoes on its surface.Different from the terrestrial planets, the Jovian planets are essentially big balls of gas. The jovian planets seemed to be formed around the same time from the solar nebula. Jupiter and Saturn are the closest in nature to each otherwise with Neptune and Uranus taking on a few of their traits. They all carry the same characteristics in their Classification. The Jovian planets are composed mainly of helium and hydrogen. They have a liquid or small rocky core. They are usually high in mass and low in density. They have many satellites and the gravity is much stronger than Earths. They also all share the same banding and zoning winds. With these characteristics defined with each description given it is promiscuous to see how the planets, Jupiter, Saturn, Uranus and Neptune are Jovian or "Jupiter - like".Bibliographies Seeds, Michael A., Foundations of astronomy procure 1994, Wadsworth inc.
