Neutron stars range in size from 20 to 40 kilometers (12 to24 miles) in diameter.
Both white dwarfs and neutron stars match the description. Neutron stars are smaller, hotter, and denser.

small GRB are believed to come from binary neutron stars, however, there have been none observed in the Milkyway.
I suggest you do some reading on both, to get an idea what a neutron star really is, and what a supergiant is. For a start, some differences are: their diameter; their density; the fact that a neutron star no longer produces any energy.
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.
All young neutron stars in reality are "pulsars". However, for a neutron star to be termed a pulsar, it's magnetic axis has to point towards Earth. (So we can see the pulse, even though all young neutron stars have a pulse, they cannot be observed from Earth.)
Some massive stars will become neutron stars. When massive stars die they will either become neutron stars or black holes depending on how much mass is left behind.
The smallest stars known are red dwarfs, which typically have masses less than half that of our Sun. These stars are the most common in the universe and can be as small as about 8% of the mass of the Sun. Despite their small size, red dwarfs can have long lifespans, burning steadily for billions of years.

Neutron stars are significant on the Hertzsprung-Russell diagram because they represent the final stage of stellar evolution for massive stars. They are located in the lower left corner of the diagram, known as the "degenerate dwarf" region, due to their small size and high density. Neutron stars help scientists understand the life cycle of stars and the different stages they go through.
Yes, there are even stars smaller than earth. Most are collapsed ancient stars that have become neutron stars and have masses slightly larger than our sun currently has.
