Is the neutron star made up of?
That's interesting. Can you tell me more about the properties of a neutron star, like its size and mass?
Sure! Neutron stars are typically only about 20 km in diameter, but can be incredibly massive - some are estimated to have up to twice the mass of our sun, despite being much smaller. They also have extremely strong magnetic fields, and can rotate extremely quickly, spinning hundreds of times per second.
