8. Milky Way The Sun is a star in the Milky Way galaxy. When viewed from the side, the
galaxy looks like a disk that is approximately 100,000 light-years in diameter (a light-year
is the distance light travels in one year) and about 1000 light-years thick (Figure P25.8).
What is the diameter and thickness of the Milky Way in meters? In kilometers? In miles?
