Anyhow, this is what I learned today:
The brightest star in the night sky.....Sirius
This star, Sirius, is part of the constellation...Canis Major (The Dog Star)
Sirius Black changed into what animal in Harry Potter? A dog!
J.K. Rowling was a pretty smart lady!

By the way....Bellatrix is also a star, the third brightest star in Orion-"The Hunter"
