    • 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
    • The density is 1x10 to the 9th km/m to the 3rd
    • White dwarfs are 200,000 times as dense than Earth
