 
 
a neutron star is the densest object
astronomers
can observe directly crushing half a
million times Earth's mass
into a sphere about 12 miles across
or similar in size to Manhattan Island
neutron stars rotate extremely rapidly
after their creation due to the
conservation of angular momentum
like spinning ice skaters polling in
their arms this lower rotational the
original Star score speeds up as it
shrinks
a newborn neutron star can rotate
several times a second
sometimes the neutron star absorbs
orbiting matter
from the companion star increasing the
rotation to several hundred times per
second
