Fun Facts

  • Hypergiant stars are the largest stars we know of. BP Crucis A is a star that is as much as 70 times the diameter of our Sun.
  • The neutron star is also called a pulsar because it emits a strong pulse of radiowaves and X-rays that we have been able to track and connect to this star system.
  • Many neutron stars are only a few miles across, and are among the heaviest stars compared to their size, with only black holes being heavier.
