The Neutron star may arise as a result of the supernova explosion. It is tiny, yet very dense. Such a star with a diameter of about 25 km can weigh twice as much as our huge Sun!
Neutron stars owe their name to what they are built of: neutrons, but also contain electrons and protons. Densely stuffed elementary particles make the object so massive. The sizes of neutron stars range from 10 km to 100 km. They are really really small. Imagine how dense the matter of such a neutron star is. A spoon of this matter can weigh up to 6 billion tons! Such a star has so much gravity. The larger one can only have a more massive object - a black hole. Neutron stars are usually simultaneously pulsars, or objects that emit pulsating radio waves. They also emit pulsating visible and X-rays. A fast spinning neutron star produces a strong magnetic field that is responsible for the pulsating radiation sent from the poles of the star. It is estimated that every thousandth star in our galaxy is a neutron star, while by 2009, about 1900 pulsars were discovered.
A neutron star is a dangerous object when it is formed during a supernova explosion, it can launch into space with great speed and find yourself on a collision course with an object. Its enormous gravitational field could have torn apart any of the planets of our solar system. Such a scenario is presented in the documentary: EVACUATION OF EARTH. I highly recommend to watch it.
