There are generally three ways a star can end its life: as a white dwarf, for smaller stars like our sun; as a neutron star, for much larger stars; or as a black hole, for the largest. The latter two are formed following the largest explosions known in the universe, supernovas.


 



Brown dwarfs are small celestial bodies that are larger than planets, but are too small to have the necessary internal nuclear fusion to ignite into stars.  One of the smallest known brown dwarfs is just six times larger than Jupiter, but it’s a free-floating body that doesn’t circle a star itself.
