Formation of the solar system
The solar system was thought to have formed with the collapse of a giant gas cloud. The giant gas cloud was thought to have been spherical in shape because like everything else in the universe, it was spinning. This was probably due to the fact that the gas it was made up with came from the stars which were spinning too. The collapse was thought to have been started by the inconsistent rise and fall of the density of the cloud, there came a point of time where there was enough material (like water, hydrogen, helium and interstellar dust) to cause the cloud to collapse. The cloud rotates faster and faster in order to conserve its angular momentum and according to the laws of physics, the faster an object spins, the smaller it becomes. As a result, the cloud begins to contract too. The cloud spins faster and faster and it spins so fast that a strong outward centrifugal force is caused and it is unable to contract any smaller. A dense disc of gas spinning around the central lump is also formed as it is simpler for matter to follow the gravitational pull along the axis of rotation (of the lump) rather than perpendicular to it as that is
The mutual gravitational pull between these meteorites causes them to be pulled nearer and nearer to each other, causing collision to be even more frequent. where the contrasting centrifugal force is supreme. And by studying meteorites, we are able to find that the solar system was formed over 4. After about, 100000 years, lumps about the size of a grain of sand would form and most of the heavy elements would have been used up. The spin of the sun is also reduced as the solar radiation from the newborn star will blow away all light gassy elements which is within approximately 6. These smaller protoplanets eventually form what are known as terrestrial planets today. Sometimes, collision between two meteorites creates enough heat to melt these meteorites to form a solid rock instead of the usual composition of tiny grains slackly wedged as one. As for the leftover planetessimals of terrestrial and Jovian planets, they form the asteroids and comets. As these tiny grains orbit around the sun, they will slowly form meteorites as they stick together. As the molecules of elements such as carbon and silicon knock against each other, they stick and gradually form tiny lumps. As the gas cloud contracts and rotates faster, the temperature of the dust and gas particles increases until the cloud is hot and dense enough for nuclear reactions to begin and thereby giving birth to a star. The terrestrial group is made up of the four innermost planets: Mercury, Venus, Earth and Mars. The immense pressure caused by the gravitational pull within these huge rocks causes the rock to liquefy and form protoplanets which are spherical in shape.
