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.
How big is the pulsar crab star?
The same size as a normal neutron star. See related question.
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.
