Solar system

            Many hypotheses about the origin of the Solar System has been suggested by experts, some of which are: Pierre-Simon Laplace, supporting Hypothesis Nebula, Gerard Kuiper, supporting Hypothesis Condensation, other theories that Nebula Hypothesis, Hypothesis planetesimals, Star Tidal hypothesis, Hypothesis condensation, Hypothesis Twin Star
            Nebular hypothesis was first proposed by Emanuel Swedenborg (1688-1772) in 1734 and refined by Immanuel Kant (1724-1804) in 1775. Planetesimals hypothesis first put forward by Thomas C. Chamberlin and Forest R. Moulton in 1900. Planetesimals hypothesis says that our solar system formed as a result of another star passing close enough to the Sun, in the early days of the formation of tidal Matahari.Hipotesis first put forward by James Jeans in 1917. Considered planets are formed due to the approach of another star to the Sun. Condensation hypothesis originally put forward by the Dutch astronomer named GP Kuiper (1905-1973) in 1950. Condensation hypothesis explains that the solar system formed from a giant rotating ball fog raksasa.Hipotesis twin star forming discs originally proposed by Fred Hoyle (1915-2001) in 1956. Hypothesis suggests that firstly our Solar System in the form of two stars of similar size and adjacent to one of them exploded leaving little pieces .
            The main components of the Solar System is the Sun, a main sequence G2 class that contains 99.86 percent of the mass of the system and dominate all the force of gravity. Jupiter and Saturn, the two largest components of the circle around the Sun, covering approximately 90 percent of the rest mass. The solar system is divided into two parts, namely governance and suryabagian in the outer solar system. The sun consists of three parts: In part bagianpertama consists of a radioactive area, local convection and the thermonuclear (Hydrogen, Helium). Baian both surface: black spots (sun spots), Fabula, granules, Sunspots (Umbra, Penumbra). Third chromosphere (corona)
            The inner Solar System is the common name that includes the terrestrial planets and asteroids. Three of the four planets (Venus, Earth and Mars) have atmospheres, all of which have meteor craters and tectonic surface properties such as volcanoes and valleys fractions. Planets are located between the Sun and the Earth (Mercury and Venus) is also called inferior planets.
            Fourth outer planets, giant planets are also called gas (gas giant), or a Jovian planet, covering 99 percent of the overall mass orbiting the Sun. Jupiter and Saturn contains mostly hydrogen and helium; Uranus and Neptune have a greater proportion of ice. All four gas giants have rings, although only Saturn's ring system that can be seen easily from Earth.
            Asteroid general object of the Solar System is made up of rock and mineral metal beku.Sabuk main asteroid located between the orbits of Mars and Jupiter, between 2.3 and 3.3 AU from the sun, thought to be remnants from the Solar System's formation that failed clumping due to the gravitational influence of Jupiter
            Comets are small Solar System bodies, usually only a few kilometers across, and is made of volatile ices. Short-period comets have orbits lasting less than two hundred years. Long-period comets have orbits lasting thousands of years. For example comet helly, Centaur,
            Satellite is a celestial companion planet. Always accompany satellite and planet rotates on its center. There are 2 satellite is the natural satellite and artificial satellite. Examples of natural satellite: moon, Titan, Io, Europa, Ganymede, Callisto, Thetys, Rhea, Dione, Triton, Larissa, Proteus, Nereid
