This figure is obtained by estimating the number of stars that have suffered a supernova explosion, a spectacular explosion of a massive star. Combined with gravitational collapse, this creates a compact, super-dense object known as a neutron star. After black holes, neutron stars are the densest stellar objects in the universe. Even denser than atomic nuclei, which is a good way to think of them, neutron stars are heavier than the Sun itself: a teaspoon of neutron star would weigh as much as 1,000 Cheops pyramids. Neutron stars can rotate at a very high speed, up to 700 revolutions per second, and have a magnetic field 12 to 15 orders of magnitude stronger than that of the Earth, which is a thousand to a million times stronger than the strongest magnetic field created by man. fields never produced.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e \u003cp\u003e\u003cb\u003eCoin motif\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e The words \"crust\" and \"core\" are marked in German on the obverse of the coin. 'Crab pulsar' is the name of a neutron star that was created from a supernova in the year 1054, while '1.4 M' refers to the solar mass of the neutron star, '30rps' to its rotation speed per second and 'r~ 10km' at its radius.
