Splet08.23.07. When the core of a massive star undergoes gravitational collapse at the end of its life, protons and electrons are literally scrunched together, leaving behind one of nature's most wondrous creations: a neutron star. Neutron stars cram roughly 1.3 to 2.5 solar masses into a city-sized sphere perhaps 20 kilometers (12 miles) across. SpletStars. Stars are massive, glowing balls of extremely hot gas (called plasma) in space. The Sun is our closest star. Although stars look small in the sky, they are actually massive objects, millions of times larger than the Earth. They look small because they are very far away. After the Sun, the nearest star is Proxima Centauri.
