Why Our Solar System Is As It Is?

Apparently, there is no reason known to us, as to why the solar system is arranged as it is. Its arrangement might have been different, as other solar systems in the universe are arranged differently. But, it has to do with the way it originated. Scientists have discovered many systems and laws of nature that possibly keep the solar system in its present pattern.

Earth as a planet, follows its own path and thus moves around the sun in its orbit. In a full year, the earth goes around the sun. The orbits of other planets are either smaller or larger than the earth’s orbit.

The astronomers are still not able to explain how the size, location, and orbit of the planets came to be. But, there are two sets of theories that mainly explain this. According to the one, the gradual change of the sun from a whirling mass of hot gases to its present brilliance and size resulted in the formation of the planets. The planets were formed as revolving masses, in the big gas and dust cloud, as it turned around.

The second thinking is founded on the idea that there was a near-collision between the Sun and another star. The pieces of Sun began to revolve around the Sun, at certain different distances. These are now planets.

It is not the point, as to which theory is correct, but the fact remains that the solar system comes to be, more or less, by a chance. How it stays on in this way? Kepler’s Laws of Planetary Motion state that the path of all planets around the Sun is oval. Its movement becomes faster, on near to the Sun. The relation between the time taken to make an orbit and its distance from the Sun is specific. Kepler’s three laws are an integral part of Newton’s Law of Gravitation, which explains how two objects attract each other. The laws of nature maintain the relationship of the Sun and the planets and the solar system remains as it is.
