Neutron stars are astoundingly dense celestial objects, packing an immense amount of mass into a relatively tiny volume. With a typical mass of about 1.4 times that of the Sun, neutron stars can have a radius of only about 10 kilometers (6.2 miles), making them incredibly compact. This extreme density results in mind-boggling gravitational forces, capable of warping space-time itself. To put it into perspective, a teaspoon of neutron star material would weigh billions of tons on Earth, showcasing the unfathomable density these stellar remnants possess.
