A neutron star is the collapsed core of a giant star.Neutron stars are the smallest and densest stars, excluding black holes, hypothetical white holes, quark stars and strange stars.
neutron stars are made up of about 95 percent neutrons. When protons convert to neutrons, they release ubiquitous particles called neutrinos. Neutron stars are made in supernova explosions which are giant neutrino factories
an average neutron star is 30 kilometers wide but just a teaspoon of them can weigh around a billion tonnes.
They are not only dense and small but super fast , they rotate about 700 times in just a second!
On average, gravity on a neutron star is 2 billion times stronger than gravity on Earth.
