I don't see a print version available anywhere, but your specific experience reminded me of this book: http://www.amazon.com/Astronomically-Correct-Twinkle-Zach-Weinersmith-ebook/dp/B00RB45C2O

It might be just a little bit too advanced - amazon says it is for ages 5-12 - but I'll let you be the judge for your child. You can also find the song on YouTube.
