It would not exist. A neutron star is what it is by virtue of the mass of the whole star. Extracting just a pinhead would revert that matter back to normal matter.
For the sake of density - as weight has nothing to do with matter outside of a gravitational body.
The denisty of a pinhead of neutron star would be the equivalant of about 100 times the mass of the Great Pyramid of Giza
What else can I help you with?
what star is smaller neutron star or white dwarf star?
A neutron star is smaller, but has a greater mass. A typical white dwarf is about the size of a terrestrial planet. A typical neutron star is a few miles across.
Why are neutron stars so heavy?
Neutron stars are so heavy because they are the compact core of a star that is 8 time the mass of our Sun. The most massive neutron stars possible are 3 times the mass of our Sun.
Why is a neutron star heavy?
A neutron star is what is left of the core of a massive star after it dies. The core collapses under the force of gravity, crushing itself from a size far larger than Earth to about the size of a city but still with a mass up to 3 times that of the sun. If it is any more massive it becomes a black hole.
Which is bigger a neutron star or a subgiant star?
A subgiant star is bigger than a neutron star. Neutron stars are incredibly dense and compact, with a radius of about 10-15 kilometers, while subgiant stars have a larger radius of several million kilometers.
What remains after supernova?
A neutron star or a pulsar, or a black hole.
How heavy is a teaspoon of a neutron star?
A teaspoon of material from a neutron star would weigh about 6 billion tons.
What is about 20 km in size?
neutron star
what star is smaller neutron star or white dwarf star?
A neutron star is smaller, but has a greater mass. A typical white dwarf is about the size of a terrestrial planet. A typical neutron star is a few miles across.
What can be formed when a star collapses?
Depending on the size of the star: a neutron star or a black hole-
What is the size of a black hole?
about 1/3 of a neutron star
Why are neutron stars so heavy?
Neutron stars are so heavy because they are the compact core of a star that is 8 time the mass of our Sun. The most massive neutron stars possible are 3 times the mass of our Sun.

Which is bigger a neutron star or a subgiant star?
A subgiant star is bigger than a neutron star. Neutron stars are incredibly dense and compact, with a radius of about 10-15 kilometers, while subgiant stars have a larger radius of several million kilometers.
What remains after supernova?
A neutron star or a pulsar, or a black hole.
Is a neutron star bigger than a planet?
Yes, a neutron star is much more massive and denser than a planet. Neutron stars are formed from the remnants of massive stars and are typically only a few kilometers in diameter, while planets can be thousands of kilometers in size.
What are two possible results of a supernova explosion?
The core of the star can collapse to form a neutron star or a black hole. The outer layers of the star can be ejected into space, enriching the surrounding interstellar medium with heavy elements.
How big is the pulsar crab star?
The same size as a normal neutron star. See related question.
