    A white dwarf is very dense: its mass is comparable to the Sun's and its volume Earth's. No nuclear fusion takes place in a white dwarf; what light it radiates is from its residual heat. [1] The nearest known white dwarf is Sirius B, at 8.6 light years, the smaller component of the Sirius binary star. There are currently thought to be eight ...
