Deep Space is outside this Solar System.

Galaxy is a generally spiral shaped collection of stars and other matter that is thought to orbit around a Black Hole. The number of stars in our Galaxy is thought to be in the billions. At light speed, Scientists say that it would take 200,000 years to cross it.
