When a star starts running out of fuel, it usually cools off and collapses into one of three compact forms, depending on its total mass, a White Dwarf a Neutron Star or a Black Hole. Their size differences are so vast. One spoonful of a neutron star would weigh about 1 billion tons. The satellite provided unprecedented views into the extreme environments around white dwarfs, neutron stars and black holes. They are much more dense than white dwarfs. In between black holes and white dwarfs are objects called neutron stars. This is the era where most of the mass in the universe is in the form of brown dwarfs, white dwarfs, neutron stars and black holes. Comparison of the Sizes of Stellar Remnants. Black holes, like neutron stars, white dwarfs and normal stars, also have strong magnetic fields that get even stronger the closer you get to the event horizon, or the point from which light cannot escape. It is difficult compare the relative sizes of black holes, neutron stars, white dwarfs, the Sun, and red supergiants on the same sheet of paper. RXTE sent data from its last science observation to the ground early on Jan. The term compact star (sometimes compact object) is used to refer collectively to white dwarfs, neutron stars, other exotic dense stars, and black holes.
