Biggest planet in our solar system: Jupiter

Jupiter PlanetThe largest planet in our solar system is the Jupiter Planet which is fifth planet from the Sun. Jupiter planet is a gas giant with the mass slightly less than one thousandth of our Sun which is two and half times mass of all other planets present in our Solar System combined. It is also classified as the gas giant along with the planets Saturn, Uranus and Neptune. These four planets is also called as the outer planets or the Jovian.

The planet Jupiter was known by the astronomers of the ancient period & also was associated with mythology and the religious beliefs of different cultures. The planet was named by the Romans after the Roman God Jupiter. This planet reaches an apparent magnitude of -2,94 when viewed from the Earth, making it on the average third brightest heavenly object in night sky after the planet Venus and the Moons. Mars planet can be briefly matched with the brightness of the Jupiter Planet at the certain points in it’s orbit.

Jupiter PlanetIf we see the composition of the Jupiter planet than it is composed of Hydrogen gas with the quarter of its mass being Helium, the planet also have rocky core of heavier elements too. Due to the fast and rapid rotation of the planet its shape is an Oblate Spheroid. The outer atmosphere is visibly segregated into the several bands at the different latitudes, resulting in the turbulence and the storms along their interacting boundaries. The prominent result is Great Red Spot, it is found that the giant storm existed since at least of the 17th century when this was first viewed by the Telescope. The Jupiter planet has faint planetary ring system with the very powerful magnetosphere. Jupiter planet have at least 63 moons with the four large moons called the Galilean Moons which was first discovered by the Galileo Galilei in 1610. Ganymede; largest of these moons, which have the diameter greater than that of the Mercury planet.

Jupiter Planet MoonsJupiter planet is primarily composed of hydrogen with the quarter of its mass being the helium. Jupiter planet has been explored on the several occasions by the Robotic Spacecraft, most notably during the early Voyager & Pioneer flyby the missions and later by Galileo Orbiter. Pluto bound New Horizons spacecraft in late of February 2007 was the most recent probe to visit the Jupiter planet. The probe used gravity from the planet Jupiter for increasing its speed. In Jovian system, the future targets for the exploration includes the possible ice covered liquid ocean on the Moon Europa.

Structure of Jupiter planet
If we talk about the structure of the Jupiter planet than it is composed of liquid matter and gaseous. As the Jupiter planet is one of the largest planet in our solar system as well as it is the largest of four gas giants too. The diameter of the Jupiter planet is about 142984 km at it's equator. The density of the planet Jupiter is about 1.326g/cm3 . Jupiter planet is consider as one of the second highest of gas giant planet. As compare to four terrestrial planets, density of the planet is lower.

Composition of the Jupiter planet
Now let's discuss about the composition of the Jupiter Planet; the upper most atmosphere of the planet is composed of hydrogen (88 to 92 percent) and helium (8 to 12 percent) by the percent volume or the fraction of the gas molecules. If we compare the helium atom and hydrogen than helium atom is about four times as mass of the hydrogen atom; the composition changes when described as proportion of the mass contributed by various atoms. Therefore the atmosphere of the planet is nearly about 24 percent helium and 75 percent hydrogen by the mass and 1 percent is covered by other elements. But while observing the interior part than it is found denser that means the distribution of the hydrogen is by 71 percent, Helium by 24 percent and other element by 5 percent. While studying about the atmosphere of the Jupiter planet it contain trace amount of the Methane gas, ammonia, silicon based compound and water vapor. Elements like ethane, neon, carbon, oxygen, hydrogen sulfide, sulfur and phosphine were also traces. Crystal of frozen ammonia is found in outermost layer of atmosphere. Benzene and other type of hydrocarbons also have traces with the help of ultraviolet and infrared.

As looking through the atmosphere proportion; Helium and the Hydrogen gases are very close to the theoretical compositions of primordial Solar Nebula. At the upper part of the atmosphere of the Jupiter planet Neon consist of 20 parts per million by the mass which is nearly about tenth as abundant as in our Sun. Helium gas is also exhausted, even though only to about the 80 percent of helium composition of the Sun. These kinds of depletion may be the result of precipitation of these elements into interior of the Jupiter planet. It is found that two to three times heavier inert gases are present in the atmosphere of the Jupiter planet as compare to the sun.

While studying with the help of spectroscopy it is thought that planet Jupiter and Saturn have the similar composition but other gas giants planet like Neptune and Uranus have relatively much more less helium and hydrogen due to the lack of atmospheric entry probes; high quality and heavier element lack for outer planet beyond the Jupiter planet.
