The Sun

I am bright and round,
golden and I shine bright.
I am the star of the day,
but I am never seen at night.

I have quite a big family,
which are the 9 planets which revolve around me.
Together we are the solar system,
and you study about me in astronomy.

From all these clues you might have guessed,
I am the mighty sun.
I make the day sunny and bright,
so you can have alot of fun.

When the day gets over,
and it is time for me to go.
You can see a beautiful sunset,
which has an extraordinary glow.

It has been a wonderful day,
and now it is time for the night.
But tomorrow when you wake up again,
once more I will be giving you light.
