A neutron star is estimated to have a radius of about 12 km. Note that a mass greater than that of our Sun is concentrated in this fairly small volume.
The description matches that of a neutron star, which is formed after a supernova explosion of a massive star. Neutron stars are incredibly dense, with matter packed tightly together. Due to their high gravitational pull, a small amount of neutron star material would have an extremely high mass.
No. While a neutron star has more mass than the sun, it is compressed into a very small area about the size of a city.
"Small but very dense" sounds like the description of a neutron star or "collapsed matter star". Theoretically, a black hole (the only thing more dense) has no physical size at all. So, "neutron star". If the neutron star is spinning rapidly, they are called "pulsars" for the radio-wave pulses that they generate.
Good sentence for neutron star - WOW ! see that;s a neutron star !!
We think that they are made of free particles and the cores may be composed of neutron degenerate matter. But we don't know for sure and it's fairly complicated. You can look up neutron stars on wikipedia for a better answer.
A neutron star is a small sphere about the size of the earth consisting mainly of neutrons and emitting regular waves of radiation as it rotates which is one of the final stages after the death of a very massive star.

The small dense remains of a high-mass star are called neutron stars or black holes, depending on the mass of the star. Neutron stars are formed when the core collapses under its own gravity, while black holes are formed when the core collapses into a singularity.
Both white dwarfs and neutron stars match the description. Neutron stars are smaller, hotter, and denser.
Neutron stars do not have fuel. A neutron star is a remnant of a star that has already died.
There's no mass range that's between "collapses into a neutron star or pulsar" and "collapses into a black hole". It'll be one or the other.
No. A neutron star ts the remnant of a massive star that exploded.
