I am the Sun I settle in the center 

Italian Scientist, Copernicus is my inventor 

Casting light is what I do

If I were elsewhere I could not lend light to Neptune 

Planets pivot around me like the hands on a clock

I cater daylight those humongous little rocks 

Geocentrism was the standard eons ago 

But in 200-300 B.C. heliocentrism was the main goal 

The geocentric model gifted earth all the attention

I was just an oversized star that didn’t even get an honorable mention

Finally, Copernicus showed Ptolomy up

He proved that I was the heart of the solar system and gave me the king's cup 

We could dwell all day on how gravitational pull works and we might not agree

But let's just say that if I wasn’t in the center, you’d be wandering without me
