DRONE Solar System Model- How far is Planet #9? [Video]

From Mark Rober:

I heart space but sometimes it can be hard to comprehend. I try to fix that in this video with junk you can find lying around your house. Also, if you’ve wondered how there could be a ninth planet that we’ve never noticed till now I try to clear that up too by demonstrating just how impossibly far away it is.
