... A neutron star is about 20 km in diameter and has the mass of about 1.4 times that of our Sun. This means that a neutron star is so dense that on Earth, one teaspoonful would weigh a billion tons! Because of its small size and high density, a neutron star possesses a surface gravitational field ab ...

But if a star is massive enough, it can leave behind something more. For this to happen though, the star must be at least I0 times the size of the sun. ...
