Our Solar System


We live in the planet Earth.Our planet is one of the nine planets that revolve periodically around the Sun.The nine planets and the Sun make up what we know as a Solar System.

Nearest to the Sun is planet Mercury,Mercury is a tiny planet that is hardly visible to the naked eyes.Further out is Venus,sometimes people called it the Morning Star or the Evening Star.It called that because it is frequently seen in the morning or evening as a very bright object in the sky.

Next comes the Earth.Earth is the only planet in the entire Solar System known to support life,it was because Earth is the only planet who have air also water and human need the both thing to survive,that why Earth is the most suitable planet for human to live.Otherwise,Earth also the most beautiful planets in the Solar System.

The fourth planet from the Sun is Mars.This planet is sometimes visible as reddish object in the night sky.Viewed through a powerful telescope one may even seen some details on the planets surface.

After Mars comes the giant planet Jupiter.It is the largest planet in the Solar System.There are a number of moons orbiting Jupiter,they can be seen through a telescope,also the surface of Jupiter shows a variety of patterns of which a huge red spot is plainly visible.The red spot is said to be many times the size of Earth.

Between Jupiter and Mars,there are exist many small object called asteroids,they are not formally visible but scientists have confirmed they exist as rock.

Next comes the Saturn.It quite a sight to view Saturn through the telescope and see distinctly the multicolours ring it is so famous for.Saturn is not big as Jupiter but it is bigger than the other planets.

Further out we have the Neptune,Uranus and Pluto.Pluto is the smallest of the planets and cant hardly be seen even with powerful telescope.Million of miles separate the planets from each other,this it only recently that human could visit our neighbour planets.So far human has set foot on the nearest planets.

If we looking at the night sky we see literally millions of the stars,the Sun is include as the stars too,so could it be that there are other Solar System too?Perhaps each star has its own solar system,we do not know,maybe one day when we are able to,we may find out.
