The Speed of Pluto | Physics with Professor Matt Anderson | M13-03

Oh, poor Pluto. Used to be a planet. Now it's not. Why? Because Mike Brown discovered that there were even bigger objects in orbit around our Sun. So if Pluto was still a planet, these others would have to be as well. Dr. Brown visited our university and I asked him (before they demoted Pluto) how many planets he thought we might have in ten years' time. His guess: 14. Boy, was he wrong. Awesome scientist, by the way. His book is called "How I Killed Pluto and Why It Had It Coming." Physics with Professor Matt Anderson
