中子星, 中子星
a highly dense and compact stellar remnant that remains after a massive star undergoes a supernova explosion, consisting almost entirely of neutrons
Example
Neutron stars are formed from the collapsed cores of massive stars after a supernova event.
The extreme density of a neutron star is such that a sugar-cube-sized amount of neutron - star material would weigh millions of tons on Earth.
Neutron stars can have incredibly strong magnetic fields, trillions of times more powerful than Earth's magnetic field.
