The diameter is about 20 or 30 km.
About the size of a city.
What else can I help you with?
What are smaller stars about the same size of a big city?
Neutron stars, the dead remnants of massive stars.
How long have Neutron stars been in the universe?
The first neutron stars likely formed some time in the first 600 million years after the Big Bang when large stars of the first or second generation died.
Do massive stars become neutron stars?
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.
What is the diffrance between stars that become white dwarfs and stars that become neutron stars?
Stars that become white dwarfs die but become black holes . Neutron stars are born from a Super Nova that stored its energy and became a neutron star.
Are all neutron stars also pulsars?
No, not all neutron stars are pulsars. Pulsars are neutron stars that emit beams of radiation that are detectable from Earth as rapid pulses of light. While many neutron stars are pulsars, not all neutron stars exhibit this pulsing behavior.
What do white dwarfs and neutron stars have in common?
Both white dwarfs and neutron stars are extremely dense remnants of the collapsed cores of dead stars.
What is a neutron star collision?
That would be a collission between two neutron stars. Since many stars are actually double stars, this can happen now and then.
How small are neutron stars?
Neutron stars range in size from 20 to 40 kilometers (12 to24 miles) in diameter.
Which star is larger neutron star or subgiant star?
A subgiant star is larger than a neutron star. Neutron stars are incredibly dense and compact remnants of massive stars, while subgiant stars are in a transitional phase between main sequence and red giant stages, typically larger and more diffuse than neutron stars.
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.
What are the heaviest things?
neutron stars
Where do pulsars originate from?
The collapse of massive stars - the same as neutron stars.
