The nearest neutron star (a collapsed star made primarily of neutrons) is about 3.00 × 1018 m away from Earth. Given that the Milky Way galaxy (Fig. P1.63) is roughly a disk of diameter ~ 1021 m and thickness ~ 1019 m, estimate the number of neutron stars in the Milky Way to the nearest order of magnitude.
