Solar System 1

I am a sun 

All planets run 

Behind me 

I agree 

There are 2 types of planets 

Inner planets 

And outer planets 

Inner planets includes mercury, Venus, earth and Mars

But on Mars there no cars

Outer planets includes Jupiter, Saturn, Uranus and Neptune 

Neptune has a perfect tune 

Stars make a constellation 

It has a calculation 

Big dipper constellation 

Gives us navigation 

Orain constellation 

Gives notification 

There are other components.
