White Dwarfs
 * Stars like the sun turn into white dwarfs after it lets out its nuclear gas
 * When the star is almost done burning its nuclear gas it gives off most of its outside layer which creates a planetary nebula
 * The core of the star becomes a hot white dwarf that measures in temperature using the Kelvin scale
 * Then the white dwarf cool down in the next billion years or so


 * White dwarfs are half as big as the sun but bigger than Earth

 * White dwarfs are 200,000 times as dense than Earth
