That's why these stars are considered one of the few Dances objects in the universe What do neutron stars do? They do not produce much heat once formed And cool down over time. The neutron stars that can be seen are mostly very hot. The surface temperature of a neutron star can be up to 600000 °C. They are so dense that a spoonful of neutron star can have a density of millions of tons. Neutron stars gravitate much more . When a neutron is going to become a star, its speed becomes very fast. They start revolving around themselves very quickly. They start doing revolutions 100 times per second.   Where to find neutron stars ?

And many of these stars have cooled down . Neu...
