Although a typical neutron star is only 20 km in diameter, its mass is 1.4 times greater than that of the Sun.

These bodies are so dense that on Earth a teaspoonful of neutron star would weigh a billion tons! As you would expect, this also comes with a gravitational field far stronger than that of our home planet. A neutron star’s surface gravity is about 200,000,000,000 stronger than that of Earth!

A neutron star is what happens when a star that is 4 to 8 times the size of the sun runs out of nuclear fuel and undergoes a supernova explosion. The central region of the star collapses in on its own gravity so and the protons and electrons are forced to turn into neutrons.

More about Neutron Stars can be found on the NASA website.
