WebApr 11, 2024 · Neutron stars are the leftover, dead cores of stars like the sun. A neutron star is so dense that the gravity on its surface is about 100 trillion times stronger than that of Earth. WebSep 23, 2024 · All that remains of the original star is a small, super-dense core composed almost entirely of neutrons -- a neutron star. Or, if the original star is very massive indeed (say 15 or more times the mass of our Sun), even the neutrons cannot survive the core collapse...and a black hole forms.
WebThey average only about 12 miles in diameter but are denser than our sun, which is more than 72,000 times bigger than a neutron star. Neutron stars got their name because their cores have such powerful gravity that most positively charged protons and negatively charged electrons in the interior of these stars combine into uncharged neutrons.
