Right now the sun is a main sequence star. When it uses up the hydrogen in its core it will become a red giant then shed its outer layers to become a white dwarf.

G2 ... or "yellow dwarf" (its really white - by the definition of "white")
YES. A typical white dwarf star is only a bit bigger than the Earth.
The sun enrgey goes in the white dwarf and the sun becomes a giant bright star then it is.
white dwarf star
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.
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.
It will first become a red giant, then turn into a white dwarf and in billions and billions of years it will become a black dwarf.
False. The sun is a yellow main sequence star.
Our Sun is currently a main sequence star. It is not a supernova, as supernovae are massive explosions that occur at the end of a star's life cycle, and it is not a white dwarf, which is a type of star that has exhausted its nuclear fuel and collapsed to a very dense state.
white dwarf
A white dwarf is the death of a medium sized star - similar to our own Sun.
No, Pollux is not a white dwarf star. It is an orange giant star that is nearing the end of its life cycle. White dwarfs are remnants of stars like the Sun after they have exhausted their nuclear fuel.
It should become a white dwarf star.
No, the sun is a main sequence star, not a white dwarf. White dwarfs are the remnants of smaller stars that have exhausted their nuclear fuel and collapsed. The sun will eventually evolve into a white dwarf in about 5 billion years.
