When stars four to eight times as massive as our sun explode in a violent supernova, their outer layers get blown off, leaving behind only the small, dense core that slowly begins to collapse on its own. These stars get their names from the protons and electrons that get pressed together under the immense gravitational field to create neutrons. Neutron stars are the smallest and densest stars; their total diameter would be roughly 20 kilometers but if you could take a teaspoon of it, then it would weigh a billion ton. The gravity on a neutron star is said to be two billion times stronger than gravity on Earth. They spin as fast as 45,000 times per minute but this value decreases over time. They also do not actively generate heat, but rather cool over time. It is estimated that there exists 100 million neutron stars in the Milky Way.
