What is a neutron star?
A neutron star is a remnant of a star after it has collapsed due to its own gravity. These stars are composed of subatomic particles called neutrons without any electrical charge. These stars could be two times the mass of the sun. The neutron stars have a very high surface gravity which could be 2 × 1011 times more than the gravity on the surface of the earth. A neutron star is very dense. It is so dense that one teaspoon (5 millilitres) of its material would have a mass over 5.5 × 1012 kg.
