A typical white dwarf has an exceptionally high density, often exceeding 1 million grams per cubic centimeter. To put this in perspective, a white dwarf's mass is comparable to that of the Sun, but it is compressed into a volume similar to that of Earth. This extreme density results from the collapse of a star's core after it has exhausted its nuclear fuel, causing electrons to degenerate and support the star against further collapse.
The typical size of a white dwarf is about the size of Earth, which is approximately 0.008 solar radii. White dwarfs are very dense objects that have collapsed from the remnants of low to medium mass stars.
White dwarf
YES. A typical white dwarf star is only a bit bigger than the Earth.
A white dwarf is the remains of an old star, but they still remain very hot and will continue to shine as a white dwarf for many millions of years until they gradually cool off to become black dwarfs. They are very dense.
A white dwarf is typically about the size of Earth, but with a mass comparable to that of the Sun. This means it is extremely dense, packing a lot of mass into a small volume.
The typical size of a white dwarf is about the size of Earth, which is approximately 0.008 solar radii. White dwarfs are very dense objects that have collapsed from the remnants of low to medium mass stars.
A cooled white dwarf is a black dwarf. I think you are thinking of a neutron star which has nothing to do with a white dwarf.
A white dwarf is much larger than a neutron star.
White dwarf
No, a typical white dwarf star is roughly the size of the Earth.
A white dwarf is much denser than the Sun. White dwarfs have a typical density around 1 million times greater than the density of the Sun, resulting in a mass similar to the Sun's but packed into a much smaller volume.

YES. A typical white dwarf star is only a bit bigger than the Earth.
A neutron star is smaller, but has a greater mass. A typical white dwarf is about the size of a terrestrial planet. A typical neutron star is a few miles across.
In 5 billion years time, our Sun will turn into a white dwarf.
