Solar System- The Controlling Factor Of Planets
This entire universe has lot of unanswered questions for which no conclusive answer has been found even in these advanced times. One such question is the factor that holds this humongous mass of planets in proper order without any change for centuries. Though scientists reply with a very modest answer that the Solar system as the key factor. The 8 planets with 4 dwarf planets surrounded by a large number of natural satellites and stars with asteroids form our milky way, the Solar system. As Sun is the central point of this Milky Way it is named as the solar system.
Mercury, Venus, Earth, Mars, Uranus, Jupiter, Saturn, Neptune are the eight planets which forms the Solar family or the solar system. This is one among the millions and millions of solar systems that are present in the vast universe. Many space missions are launched to know more and get the complete knowledge about this massive universe. It is believed that the existence of this kind of planet Earth on which man can survive could be found and there are many explorations that many countries are undertaking now. This belief is strengthened with the supportive information about the presence of Extra- terrestrial living organisms and Unknown flying objects that people have noticed or seen in different parts around the world.
The sun being the prime source of energy on which the Milky Way is based it serves as driving force around which all the planets move. Sun is a mass made up of helium, Hydrogen and many other gases. These gases form the upper layer of Sun. Based upon the distance from the sun, the position of various planets in the solar system is calculated. The planets which takes less than 2 AU to go around the Sun is said to be Inner planets. Mercury, Venus, Earth, Mars are the planets that constitutes the inner layer of the solar system. The remaining planets that take more than 2 AU are the outer planets and are made up of the planets Uranus, Jupiter, Saturn, and Neptune. There are the asteroids which is a heap of particle mass in the outer space and which forms a belt in between the planets.
The age of our solar system is estimated to be 4 lakh years old and its size hasn’t been properly sketched out yet by scientists. According to the scientists, the shape of full solar system is supposed to be like a hemispheric current sheet which forms the planetary positions. There is some uncertainty for many in this regard as to how and where the smaller and minor planetary bodies like comets, centaurs, scattered discs, heliopause, are positioned in the solar system. But some scientists have come out with the “big bang theory” which does give and answer to the doubt regarding the position of smaller planetary bodies. On the whole, the entire solar system seems to be a mystery that has not fully been unraveled and is in the process of being so as the inclination to explore is always entrenched in man.
