Question
A particular spiral galaxy can be approximated by a thin disk-like volume 35 Thousand Light Years in radius and 8 Hundred Light Years thick. If this Galaxy contains 790 Billion stars, estimate the average distance between the stars in this galaxy. Hint: calculate the average volume per star in cubic Light Years, and then estimate the approximate linear dimension across such a volume. (Indicate your answer to one decimal place.)
