“A typical neutron star has a mass between 1.35 and about 2.0 solar masses, with a corresponding radius of about 12 km if the Akmal-Pandharipande-Ravenhall equation of state (APR EOS) is used. In contrast, the Sun’s radius is about 60,000 times that. Neutron stars have overall densities predicted by the APR EOS of 3.7×1017 to 5.9×1017 kg/m3 (2.6×1014 to 4.1×1014 times the density of the Sun), which compares with the approximate density of an atomic nucleus of 3×1017 kg/m3. The neutron star’s density varies from below 1×109 kg/m3 in the crust increasing with depth to above 6×1017 or 8×1017 kg/m3 deeper inside. This density is approximately equivalent to the mass of the entire human population compressed to the size of a sugar cube.”
