Dense remnant of a massive star after a supernova.

pulsar

A neutron star is a type of stellar remnant formed from the collapsed core of a massive star after a supernova explosion. These objects are incredibly dense, with a composition primarily consisting of neutrons.

/ˈnjuːtrɒn stɑːr/

The term 'neutron star' was coined in 1932 by Walter Baade and Fritz Zwicky.

A neutron star is what's left over when a giant star explodes, squishing all its matter into a tiny space like squeezing the sun into a city.

What is a neutron star? It's the collapsed core of a massive star after a supernova
How dense are they? A teaspoonful would weigh billions of tons
What happens if you get too close? The intense gravity and radiation would be deadly
