Chapter 1, Problem 56P
The distance from the Sun to the nearest star is about 4 × 1016 m. The Milky Way galaxy (Fig. P1.56) is roughly a disk of diameter ~ 1021 m and thickness ~ 1019 m. Find the order of magnitude of the number of stars in the Milky Way. Assume the distance between the Sun and our nearest neighbor is typical.
