YES. A typical white dwarf star is only a bit bigger than the Earth.
A white dwarf is smaller, cooler, and denser than the star it evolved from. It is the remnant core of a star like our Sun after it has exhausted its nuclear fuel and collapsed under gravity.
A supergiant is much larger than a white dwarf. A supergiant can be 10 to 70 times the size of our Sun, whereas a white dwarf is only about the size of the Earth.

No, the sun will not become a white dwarf in the next 20 years. It is estimated that the sun will become a white dwarf in about 5 billion years as it reaches the end of its life cycle.

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.

The obvious reason is that the specific star has bigger density compared with the Sun. For example, that star could be a "white dwarf star". A white dwarf mostly contains "electron degenerate matter", which is very dense. A white dwarf is a small dense star.
A supergiant is much larger than a white dwarf. A supergiant can be 10 to 70 times the size of our Sun, whereas a white dwarf is only about the size of the Earth.
the sun, Pluto is a very cold dwarf planet, which is very small and was just recently proven a dwarf planet.
The end of the Earth will probably come way before that. The Sun will get hotter and hotter for a while, and in about half a billion, or perhaps a billion years, it will get so hot that no life will be able to survive on Earth.
Luminosity will also depend on the surface area. The Sun has about 10,000 times the surface area of a typical white dwarf.
False. A white dwarf star is much smaller in size compared to the sun. A white dwarf is typically about the size of the Earth, whereas the sun is much larger, around 100 times wider and more massive than a white dwarf star.
