Detailed explanation-1: -neutron star, any of a class of extremely dense, compact stars thought to be composed primarily of neutrons. Neutron stars are typically about 20 km (12 miles) in diameter. Their masses range between 1.18 and 1.97 times that of the Sun, but most are 1.35 times that of the Sun.
Detailed explanation-2: -Most of the basic models for these objects imply that neutron stars are composed almost entirely of neutrons (subatomic particles with no net electrical charge and with slightly larger mass than protons); the electrons and protons present in normal matter combine to produce neutrons at the conditions in a neutron star.
Detailed explanation-3: -This incredible density comes about because of how neutron stars form. A star is held together by a balance between gravity trying to contract it and an outward pressure created by nuclear fusion processes in its core. When its supply of fuel is exhausted, gravity takes over and the star collapses.
