The Sun has always been classed, chromo-fashion ( Color wise) as a Yellow Star. one might poetically talk of golden sunshine, etc. a Red Star or sun is quite different and actually produces less heat and energy at a lower intensity and more expansion. One of the Pagan religions ( I believe it was Zoroastrianism) had the odd doctrine that Mankind evolved--or came into being, under a RED SUN. Fire worship and Red Solar decorations were used by this faith. who knows?
A red giant star is much larger and brighter than the Sun. It is in the later stages of its life cycle when it begins to expand and cool down. Eventually, it will shed its outer layers and become a white dwarf.
There are a lot of these. They are mainly the "Red Giant" and "Red Supergiant" stars.
A red giant can become brighter if its core temperature increases due to increased fusion reactions. Even though the surface temperature decreases, the overall luminosity of the star can increase if the core fusion rate intensifies, producing more energy.
Our Sun will eventually become a red giant, not a red supergiant. As it exhausts its hydrogen fuel in about 5 billion years, it will expand and cool, turning into a red giant. A red supergiant, on the other hand, is a larger star that has significantly more mass than the Sun and undergoes a different evolutionary path.
Much Much Much bigger. But the Sun will turn into a Red-Giant in a couple billion years.Your welcome!

No. The sun will become a red giant in about 5 billion years.
No, it is much less bright.
super-giant star
Yes, UY Scuti is a red supergiant star, which is a type of star that is larger and brighter than a red giant star.
Three possibilities: It is brighter (some are brighter than others), it is bigger, or it is closer to earth.
Our Sun will eventually become a Red Giant towards the end of its life.

When the sun becomes a red giant, it will expand to about 100 times its current size.
