LYRICS:
I am Venus
I’m the second planet from the sun
And I’m the slowest rotating one
Of all the planets in our system
Now learn and have some fun
243 earth days
is how long it takes
for me to orbit the sun
That makes just one of my days
I’m 900 degrees
Yeah thats Fahrenhite
Im the hottest planet in the
solar system that’s right
The sun sets in my east
and comes up in my west
do to Retrograde Rotation
I spin backwards the best
I’m the third brightest object
to the naked eye
from the planet of earth
when you look up in the sky
I am Venus
I’m the second planet from the sun
And I’m the slowest rotating one
Of all the planets in our system
Now learn and have some fun
Carbon Dioxide
and Sulfuric Acid clouds
Is what makes up my atmosphere
and for this I am very proud
Volcanos, mountains,craters
and some big lava plains
Are what make up my bumpy surface
And my clouds make no rain
I was named Venus
after the goddess of love
The Romans gave me my name
do to my brightness above
I am Venus
I’m the second planet from the sun
And I’m the slowest rotating one
Of all the planets in our system
Now learn and have some fun
