Description:
Among the densest stellar objects in the universe, neutron stars are heavier than the sun itself. A superb representation of this unique galactic phenomenon, this little beauty weighs considerably less.
With a half-sphere at its center that curves inward on one side and outward on the other, the latest piece in The Uncharted Universe series is designed to be a simplified representation of this unique galactic phenomenon: the neutron star.
Reach for the stars!
There are thought to be up to a billion neutron stars in the Milky Way. This figure is obtained by estimating the number of stars that have undergone 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 of putting it, neutron stars are heavier than the Sun itself: a teaspoonful of neutron star would weigh as much as 1,000 Cheops pyramids. Neutron stars can rotate at very high speeds - up to 700 revolutions per second - and have a magnetic field 12 to 15 orders of magnitude stronger than that of the Earth,
Coin motif
The words "crust" and "nucleus" are marked in German on the obverse of the coin. crab pulsar' is the name of a neutron star created from a supernova in the year 1054, while '1.4 M' refers to the neutron star's solar mass, '30rps' to its rotational speed per second and 'r~ 10km' to its radius. On the reverse of the coin, the neutron star swells through a colored imprint and a stylized representation of its magnetic field.
