How did Saturday Sunday and Monday get their names?

My understanding is they came from the ancient Pagen worship and their gods. This information I have seen on the History channel. Saturday - Saturn Day Sunday - Sun Day Monday - Moon Day Tuesday - The Pagen God Tews (Tews Day) Wednesday - The Pagen God Wooden (Woodens Day) Thursday - The Pagen God Thor (Thors Day) Friday - The Pagen God Frie (Fries Day)
