Are black holes bigger than neutron stars?

Neutron stars are dead stars that are incredibly dense. A teaspoonful of material from a neutron star is estimated to weigh around four billion tonnes. Both objects are cosmological monsters, but black holes are considerably more massive than neutron stars.

Is the density of a neutron star greater than a black hole?

Scientists have discovered an object in a cosmic collision that is denser than previously detected neutron stars but still far less dense than known black holes, challenging the accepted description of neutron stars and black holes, two of the many forms of massive, dying stars in the universe.

How big must a neutron star be to become a black hole?

The infalling outer envelope of the star is halted and flung outwards by a flux of neutrinos produced in the creation of the neutrons, becoming a supernova. The remnant left is a neutron star. If the remnant has a mass greater than about 3 M ☉, it collapses further to become a black hole.

Are black holes smaller than neutron stars?

For decades, astronomers have been puzzled by a gap in mass that lies between neutron stars and black holes: the heaviest known neutron star is no more than 2.5 times the mass of our sun, or 2.5 solar masses, and the lightest known black hole is about 5 solar masses.

What determines black hole or neutron star?

Originally Answered: What determines if a collapsed star turns into a black hole or a neutron star? Only one thing – the mass of the star. If the mass of the supernova remnant is below 2.16 times the mass of our Sun, it will collapse into a neutron star.

Do black holes have a diameter?

The math of calculating the diameter of a black hole could not be easier. A black hole with the mass of the sun has a diameter of about 6 kilometers, or 4 miles.

What is the radius of black hole?

Black hole classification by Schwarzschild radius
