The solar system is formed by the sun, the planets, the satellites and some other small objects that turn around. The current theoretical models, with lagoons, predict that The birth of the solar system took place around 5,000 million years ago And there is now in the middle of his life. Moreover, the sun lives its most stable period for years. In it there were the right conditions for life to originate and evolve. Because The end of the sun will take place with a long painFor the earthly, if we do not make barbaricities with our planet, we have a living for less than 5,000 million years.
The sun was, like most stars, Of a cold cloud of hydrogen, helium and some heavier materials Usually coming from the explosion of a massive star (SuperNova). The planets were also born from this cloud. Due to a disturbance, probably from another supernova, the cloud began to contract. As the cloud contracts more, the rotation speed increased until He formed an album. In this, dust particles clashed with each other and, because of gravity, produced small groups. These groups continue to attract particles, grew in size and gave rise to the planets. The Sun -driven interior planets lasted several hundred thousand years. The outside, between around 10 and 20 million years.
The sun was also formed during this process. It is thought that, after a million years of his appearance, a so -driven solar wind of the album all the material that had not collected on the planets. The power of that wind decreased with the distance, so The interior planets are more rocky and the most gaseous exterior.
The sun was also born from the contraction of a volume of cold cloud particles. While that volume is contracted, It increased its temperature until it reached 12 million degrees. At that time, the nuclear fusion reaction started that connects two hydrogen cores to form one of helium. So there was a time when the expansion as a result of heat produced with merger -nuclear energy was leveled for the contracting force as a result of gravitation. At that moment the sun reached a balance situation.
From birth, The sun consumed half of the hydrogen it contained And the helium formed in the merger reaction accumulates itself in the middle. There will be a time when hydrogen will only be in a superficial layer. Then this star will increase its size until it becomes a red gigantic star and will swallow to mercury, venus and, possibly for the earth, the center will reach 100 million degrees and start the merger of the helium, which gives rise to oxygen and carbon. Fijnely, the sun will throw a lot of material in the room, it will cool and a white dwarf that is the size of the earth.
