THE SOLAR SYSTEM
THE SOLAR SYSTEM
The solar system was formed about 4,600 million years ago. It is located in the Orion arm of the MILKY WAY galaxy,around two-thirds away from the central bulge,about 27,000 light years from the central of the galaxy. It takes the solar system about 220 million years to orbit the galaxy once. The solar planets can be decided into an inner system of four small,solid planets made up of materials similar to that the Earth. The outer system of four large planets ,knows as the gas giants,has ring and lots of moons. The gas giants are made up mostly of hydrogen, helium,frozen,water,ammonia,methane,and carbon monoxide. Pluto does not belong to any group but is a tiny rocky body at the edge of solar system. Some people think it is a giant comet rather than a planet. Its composition is similar to a comet (ice and rock) but its orbit is different from the other comets and planets. Between these two planetary system is a belt of asteroids containing pieces of rock of varying size.
Solar system has 8 planets and 3 dwarf planet. These planets are :-
1. Mercury.
2. Venus.
3. Earth.
4. Mars.
5. Jupiter.
6. Saturn.
7. Uranus.
8. Neptune.
The 3 dwarf planets are :-
1. Pluto.
2. Make Make.
3. Eris.
