The solar system is the gravitational bound system that comprises of sun and the objects that orbits the sun directly and indirectly. Its age is around 4.568 billion years. Its location of the solar system is local interstellar cloud. The solar system is tucked away with the corner of Milky Way at the distance of 30000 light years from the center of the galaxy.
The solar system consists of nine planets and these planets are known as the wanderer. Though stars do have the fixed position and the planet shift their position from one place to another but that too are not stationary.
The population of solar system consists of
- One sun
- Eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto)
- Natural satellites (175 Planetary and 297 Minor Planetary)
- Minor Planets 707664
- Comets 3406
- Identified satellites 19
The solar system was formed many billions years ago from the gravitational collapse of a giants interstellar molecule cloud. It is composed of sun, planets, comets, satellite, etc. it is primarily composed of rocks and metals. There are two giants available, that is, gas giants and ice giants.
Gas giants are mainly composed of hydrogen and helium whereas the ice giants are composed of volatile’s like water, ammonia and methane. Solar system is very huge and the Jupiter is the largest planet in the solar system.

History of Solar System
In the starting years, the concept of solar system was difficult to be understood but later after the detailed study in mathematics and physics in seventeenth century, solar system was accepted. Majorly the idea was accepted that the earth moves around sun.
Later the invention of telescope made it easier to discover the other planets and moons. The improvements in the telescope made for the investigation of geological phenomena such as mountains, clouds, dust storms and ice caps on other planets.
Types of Solar System
- Inner Solar System: It comprises of terrestrial planets and the android belt. It is composed of silicates and metals. The objects of inner solar system are close to the sun and the inner planets have dense, rocky composition, few moons, and no ring system. There are metals in the crust like iron and nickel. These are generally four inner planets, that is, Mercury, Venus, Earth and Mars.
- Outer Solar System: The outer solar system consists of the planets Jupiter, Saturn, Uranus and Neptune.
Generally everything in the solar system revolves around the sun as sun consists of the ninety eight percent of the materials available in the solar system. Sun is the head of solar family and compared to millions of other stars it is a medium sized star with average brightness but it appears to be larger and brighter because it is much more nearer to the earth than other stars.
The heat and light energy makes sun shine and the planets and other objects in the sky reflect a part of sunlight falling on them due to which they are visible to us. The earth too reflects the part of sunlight falling on it and that is the reason when we look earth from moon or other planets it looks bright.
The interaction between the earth and sun drives mainly four season, that is, winter, summer, autumn and spring. It also drives the ocean currents, climate, weather and radiation belts.
It is said that the larger an object more will be the gravity and because sun is having is having very powerful gravity; it attracts various objects near it. The planets orbit in the same direction goes in clock wise direction from North Pole and so the planets like Venus, Uranus and Pluto also rotate in the same direction.
In the solar system, earth is the only planet gifted that has life. Many researchers going on other planets in search of life like Mars but the results are not satisfactory. The men is moving ahead towards the advance technology that would definitely leads forward to quench the thirst for knowing the facts that remained unknown.
