When a massive star reaches the end of its life, it is possible for a supernova to occur. This may result in the formation of a very small, but very dense, neutron star, the density of which is about the same as a neutron. A neutron has a mass of 1.7 x 10-2 kg and an approximate radius of 1.2 x 10 5 m. The mass of the sun is 2.0 x 1030 kg. Determine the radius R of a neutron star that has twice the mass of our Sun and the same density as a neutron. 1.27 x104 R = m Incorrect
