What is Neutron Star?

Neutron Star

The neutron star is the collapsed remains of a massive star after its supernova explosion. Neutron stars get their name from the large number of particles they contain, which are neutrons, which are stable elementary particles, and not normally found in stars. A neutron star is a star with a mass of about 1.4 solar masses. This is a very large mass for a star.
We all know about neutron stars. They can be created when a large star dies in a supernova, and collapses to form a huge ball of neutrons. For a long time, physicists thought that they could only form when a massive star dies at the end of its life. But in recent years, astronomers have discovered other ways of creating neutron stars, such as in a neutron star merger, where two neutron stars spiral together and merge.
A neutron star or neutron star is a common type of star that has collapsed down to be the size of a small city. They are the remains of an extremely massive star that has gone supernova. Neutron stars can be as small as a few kilometers in diameter, with a mass of about one to two Suns, and they can be as massive as several times that. They are extremely dense, reaching a density of about 2.1×10^15 kg/m^3 and a temperature of over 3×10^11 K. They are found throughout the universe, often in binary systems, which allows us to study their properties in more detail.
Why a Neutron Star is Cool. A neutron star is the dense remains of a star that has burned through its fuel. A neutron star has a diameter of about 15 miles, yet its mass is usually about 15 suns. A large fraction of the mass is a ball of neutrons, which is called the neutron star.

Neutron Star Surface Gravity
A neutron star will have a surface gravity of up to 1.5×10^11 m/s^2. As a result, you will feel less gravity than in this situation! You will feel 1.5×10^11 m/s^2 = 10g. What is 10g? It is the acceleration you feel at the surface of the Earth.
How big can a neutron star be? How dense is it? Well, it turns out that some neutron stars can be as large as 15 miles in diameter and with a mass of about 15 suns. That is about the size of a small city.
The gravity of the neutron star is intense. The gravity is about 100 times more powerful than the gravity on the surface of the Earth. It is so strong that if you jumped off a neutron star, you would go flying through outer space at 9.8 kilometres a second. The gravity is only about 3% less than the gravity of the Sun, but it is 1.6% the mass of the Sun.
Most neutron stars have a surface gravity of 2×10^17, which is about 150 g. The mass here is the mass of the neutron star as a whole, not the neutron star you live on. The density of a neutron star is much higher than that of the earth. Most stars have a density of about 2×10^3 kg/m^3, and the neutron star has a density of about 2×10^15 kg/m^3, which is about 200 times as dense as lead. This means a neutron star is about the size of a city.
Neutron star surface gravity is a measure of the force of gravity at a neutron star’s surface. It is a lot stronger than at the surface of the Earth, and about 10 times stronger than on the surface of a neutron star. It is the same as a surface gravity of 1G, but in other respects it is like a surface gravity of 0G. Because of the high density and temperature at the surface, objects accelerate upwards to the star’s surface. But at the surface of a neutron star, because the gravitational force is so strong, objects actually fall towards the center.
