 __White Dwarf__

Define: A White Dwarf is a small star which is composed for electrons, you can also call it a degenerate dwarf.



 Description: White Dwarfs are thought to be the final stages of all stars life, which means our sun now is about 4 billions years old, in about 4-5 billion years it will run out of hydrogen and expand into a red gaint then it will come back in and form it's self into a White Dwarf. When a White Dwarf is formed its it very hot but since there is no energy it will gradually cool down into a Black Dwarf. The reason why the White Dwarf has no energy becuase the material in the White Dwarf dont react which with each other therefore the sun/star has no source of energy.
