My son absolutely loves this song from the YouTube channel KIDSTV123. It’s a rather depressing ditty about our solar system.. each planet, and the sun, sings about its surface.. set to a sad melody. When Ayden sees it he is just in awe.. I am, somewhat, too.. It sticks in your head, in a strange and somber sort of way… 

And take note: Pluto has not been included.
