Neutron+Star

A neutron star is formed from the fallen remains of a massive  star. Models expect that  neutron   stars contain mostly of neutrons, and so that’s how it got its name. A neutron star is one of the few likely  conclusions   of a   stellar evolution. A neutron star has very strong gravity.
 * __Neutron Star__**

A usual neutron star has a  mass between 1.35 and 2.1 solar masses, with a equivalent radius between 20 and 10 km , in that order it is 30,000 to 70,000 times smaller than the Sun .Therefore, neutron stars have and overall densitie to those encountered in the nucleus of the atom. Most neutron stars have been found as radio pulsars, the vast majority of the energy produced by neutron stars is in very high energy photons
