Why isn’t Pluto a planet anymore?

Why isn’t Pluto a planet anymore? C.P. Grey gives a great animated explanation, with a bit of history and a lot of information about the scale and relationships of the types of planets (and other objects) in our solar system.

Though it’s labeled as a dwarf planet now, Pluto is still a planet in all of the kid’s old second-hand and retired library books, so this video was pretty important for us to understand. And even though it was jam packed with some fast moving info for a four year old, reviewing the video gave us a good chance to do lots of drawing and diagramming. Have crayons, markers and paper on hand for after!

From the archives, more planets and more space!
