An average diameter of a star is approximately 109 m and an average diameter of a galaxy is 1021 m. Considering the given data, apply a sense of scale calculation to determine if when a galaxy’s diameter is scaled down to the length of Manhattan (21.6 km long), would the star be larger or smaller then you?
