Why Is Pluto Not A Planet? (2014x5)
:
Pluto's not a planet. We're sorry, but we think it's time you move on. If you've gone through all your breakup music and Meg Ryan movies, and you still can't get over it, then SciShow Space will get out the ice cream, cuddle up with you on the couch, and talk about how this could have happened.
