List of neutron stars

Zooming to RX J1856.5−3754 which is one of the Magnificent Seven and, at a distance of about 400 light-years, the closest-known neutron star

Neutron stars are the collapsed cores of supergiant stars.[1] They are created as a result of supernovas and gravitational collapse,[2] and are the second-smallest and densest class of stellar objects.[3] In the cores of these stars, protons and electrons combine to form neutrons.[2] Neutron stars can be classified as pulsars if they are magnetized, if they rotate, and if they emit beams of electromagnetic radiation out of their magnetic poles.[4] They may include soft gamma repeaters (SGR) and radio-quiet neutron stars, as well as pulsars such as radio pulsars, recycled pulsars, low mass X-ray pulsars, and accretion-powered pulsars. A notable grouping of neutron stars includes the Magnificent Seven.
