What is a Neutron
Star? Neutron
stars are very dense and spin very fast and
are typically only 10-15 km in radius. Because neutron
stars form from burnt-out stars,
they do not glow.

stars are compact objects that are created
in the cores of massive stars during supernova
explosions. The core of the star collapses,
and crushes together every proton with a corresponding electron turning
each electron-proton pair into a neutron.
