Solar system (Solar System) is a system that consists of. The Sun is the center of a planet (Planets), there are 9 planets, their satellites moons of each. (Moon of sattelites) asteroid (Minor planets), comets (Comets) meteorites (Meteorites) group, as well as dust and gas, which are moving in orbit. Under the influence of the Sun gravity of the solar system not only is required. If there are other ลักาณะ that is called the solar system are the same, but this would mean that in our solar system. The size of the very vastness of the solar system. Compared to the distance between the Earth and the Sun, which has a distance of about 150 million kilometers, or 1 astronomical unit.
That is, the solar system, there are long distances to reach the orbit of Pluto is a planet of the solar system's smallest which is far short of the 40 x 1 units of astronomy and also far away again until Dong Comet (Oort's Cloud) that ut might be up to 500,000 times the distance from the audits.Omission of the Sun with The Sun is a mass of more than 99 percent of all the mass in the solar system, the rest will be the mass of the planet thewatthu, which contains comets and asteroids, meteorites, including dust and gases that drift between the planets, with each attraction (Gravity) force is what should.Thewatthu, bakhum solar system on all kotraeng that is based on movement. Newton's gravity. The sun comes out with power diffusion rate of approximately 90000000000000000000000000 calories per second is energy thermo nuclear reactions are caused by the change of hydrogen is helium, which is the heat source to the stars. Although the various planets, the Sun will lose hydrogen to reach 4,000,000 tonnes per second, but scientists still believe that the Sun is still spreading energy. In this same rate for billions of years.
