How Big Is A Neutron Star?


NASA has created this image to show the relative size of a neutron star.

…the crushed core of a star that has exploded as a supernova and packs half a million times the mass of Earth.

It’s smaller than Brooklyn.

    It’s tiny but incredibly dense – one spoonful would weigh thousands of tonnes. The reason a neutron star is so compact is because it’s gravitational attraction is massive due to its density – it collapses to the extent the normal electrical repulsion is overcome and neutrons are squashed together/ A black hole, by contrast, can be even smaller!
