What is a white dwarf

A white dwarf is a very small dense star that is the size of a typical planet. It is formed when the star has exhausted all of its fuel and layers.

A white Dwarf is a n animal, plant or another thing much smaller than the usual of its sort.

White dwarfs are stars that have burned up all of the hydrogen they once used as nuclear fuel. Fusion in a star's core produces heat and outward pressure, but this pressure is kept in balance by the inward push of gravity generated by a star's mass.
