SOLAR SYSTEM
The ancients believe that there were just seven planets including the: Sun, Moon, Venus, Mars, Jupiter, and Saturn and was believed that these planets were very important in the affairs of mankind. The astrological study of their positions among the stars at the moment of one’s birth was supposed to give information about his/her fate. The general character of a person was thought to be determined by which planet she/he was “born under” according to the calculations of astrologers, such superstitions continue in modern time.
As what i have studied and read, I conclude that there is more information behind the solar system that I read a while ago and part of it is the origin of the solar system. It began with a cloud of interstellar gas and or dust is disturbed and collapses under its own gravity. The disturbance could be, for example, the shock wave from a nearby supernova. And then as the cloud collapses, it heats up and compresses in the center. It heats enough for the dust to vaporize. The initial collapse is supposed to take less than 100,000 years.
The Solar System is composed only of solid proto planetary bodies and gas giants. The gas cools off enough for the metal, rock and ice to condense out into tiny particles. The metals condense almost as soon as the accretion disk forms; the rock condenses a bit later. We all know that the solar system was composed of 8 planets, let’s all know first the inner planets, the nearest in the sun is Mercury the smallest planet, next to mercury is Venus which is the hottest planet, Earth is the largest and densest of the inner planets, and Mars is smaller than Earth and Venus, now let’s go to the outer planets which is Jupiter composed of largely of hydrogen and helium , Saturn second largest moon in the solar system, Uranus is the lightest of the outer planets, and Neptune smaller than Uranus. Now I have learned more about our solar system.
