Neutron stars are among the most interesting objects in the universe

Neutron stars are formed by the gravitational collapse of other massive stars but their mass is not enough to form a black hole.

  • They are among the tiniest objects known in the universe(~10-13 kilometer radius).
  • Have a mass of a few times that of the sun! (~1.4-2 solar masses).
  • They spin around as rapidly as 700 times a second. That’s ~42,000 times a minute.
  • Have a density of 3.7×10^17  to  5.9×10^17 kg/m^3. That’s approx 10^14 times more dense than the sun, comparable the the density of an atomic nucleus!
  • This density is approximately equivalent to the mass of a Boeing 747 compressed to the size of a small grain of sand.
  • One teaspoon of the material of a neutron star would weigh 5 billion tonnes. That’s more than the weight of everyone on the earth combined!
