Pluto, furthest away from the Sun
And too cold for life to get ahead
Is also named after a Roman god
The Roman god of the dead

Pluto has a very big moon
That is nearly just as large
Charon is its name
(pronounced ‘karon’)
Like twins, they are almost the same
So it’s hard to tell who’s in charge!

Pluto and Charon, in orbit together
Distant from all, they frolic and sway
Perhaps, long ago, they were passer-bys
That love of gravity won’t let get away

Think of the great distances of space
Think of moving at the speed of light
(300,000 kilometers per hour)
For light to get from the Sun to Earth
It takes a bit of time
Over 8 whole minutes worth

8 minutes might seem like quite a while
But imagine Pluto! Wayout there!
How long does it take
For a single sunny ray
To travel from
2 BILLION kilometers away

Figure it out and you can say
It takes about two hours
For a sunny ray to reach Pluto
As it travels on its merry way

Pluto is so very far
Which means it's not so very near
So for Pluto to make just one
Single orbit around the Sun
It takes over 200 years!
