B is for Black Hole -

Definition- A black Hole is a massive object in space that is so dense.

Black Hole looks like a giant black circle and work like a vacuum. If you watch closely as you vacuum your room you can see the dirt get sucked close to the vacuum and that is pretty much what a black hole does.
