Neutron stars are some of the densest object in the universe. They form during supernova explosion and are very small compared to other astronomical objects. You can assume 5x10^17 kg\m^3 as the average denisty of a neutron star. The Earth has a total mass of about 5. 97x10^24kg. What would be the diameter of the Earth if it had the density of a neutron star?
