The remnants of a star that collapsed under its own gravity after going
supernova.
Neutron stars are very small stars (Usually 30km in diameter) with an extremely high density of 1.4 to 2.16 solar masses. These stars also emit extremely powerful
magnetic fields that could rip planets apart.
PSR B1509-58 is classified as a
pulsar, which is a type of
neutron star that spins rapidly, so much that it can complete a rotation in milliseconds.
