LYRICS:
My name is Neptune
The 8th Planet
from our burning Sun
I got 6 rings
Made up of dust
And some rocky chunks
I got my name
From the Romans
It means God of the Sea
My upper atmosphere
has methane
Thats why I have blue on me
Hydrogen and Helium
are the rest of my atmosphere
I have 13 moons
with one still waiting
to confirm its here
Minus 392 degrees
an average day on me
And my winds are the strongest
than any planet in our system see
My name is Neptune
The 8th Planet
from our burning Sun
I got 6 rings
Made up of dust
And some rocky chunks
About 165 earth years
makes one Neptunian year
57.7 earths could fit
in my giant Sphere
2.8 billion miles is my distance
from our sun
1 day on me is about
16 earth hours of cold fun
No Life as we know it
could survive on me
I’m the 4th largest planet
in our system you’d have to agree
My name is Neptune
The 8th Planet
from our burning Sun
I got 6 rings
Made up of dust
And some rocky chunks
