The solar system caused by the dust and gas in the space which is called "the solar nebula" (Solar Nebula) together when, about 4 600 million years ago. The scientists calculated from the fusion rate (hydrogen into helium in the sun). When matter more gravity between mass increase as well. The dust and gas, forming a plate rotating according to the principle of angular momentum conservation, as shown in the picture at the 1 gravity increases to create pressure at the center and high temperature to 15 million K. Light nuclear fusion reactions. The atom of hydrogen into helium melting. The sun rise is stellar.The material around the sun (Planetisimal). Keeps spinning and orbit around the sun, with the existing momentum The mass in orbit each layer together as a planet. The influence of gravity makes the material around it. Approaching the planet from all directions. If the direction of the movement has deep corner hit the planet. The planets are large and have mass increase. But if the angle of crashing too shallow, it may make ricochet into orbit. And gathering became the moons, as that big planet, such as stars and moons Thursday Saturn has several planets. Because it is a large planet mass has much so there is gravity. With mercury, which is a small planet has a mass less, so there is little gravity has no moons. The asteroid and comet that are shaped like a meteor. Because of a small low mass stars Gravity cannot overcome the bond strength between matter to the merger into the sphere.Evidence theory, the birth of the solar system is. If you look from the top of the solar system (Top view) will notice that both the sun, planets and the moon of nearly all stars. To revolve in the counterclockwise. And orbit around the sun in a counter-clockwise direction * *. And if viewed from the side of the solar system (Side view) will notice that the planets and moons of nearly all stars. The orbital plane close to the ระนาบสุริยวิถี (Ecliptic plane) this is due to the entire solar system, กำเนิดขึ
