The Sun and its Eight Orbit Planets in our Solar System

 

After watching Interstellar that movie, I’ve got more amaze by the massive universe that surrounding us. As we human live in Earth and Earth is one of the solar system planet, and our solar system is just a very tiny little bit of thing inside the huge huge massive universe.

As we live in here, I think is better to have basic understanding about what consists in our solar system too. During my school time, solar system is consist of 9 planets, but the last planet, namely Pluto, had got omitted away. Why Pluto get ignore in the solar system? Because it was found out to be one of the big icy body at the outer solar system disc, namely Kuiper Belt. One of the fact to know is our solar system formed about 4.6 billion years ago according to space expert in Earth.

Below are some basic facts and figure about our big star The Sun and the other orbiting 8 planets according to their orders.
