Is the sun dying 2020
For about a billion years, the sun will burn as a red giant.
Then, the hydrogen in that outer core will deplete, leaving an abundance of helium.
Astronomers estimate that the sun has about 7 billion to 8 billion years left before it sputters out and dies..

What is the 3rd biggest star
The third-largest star in the Universe belongs to the constellation Cepheus in the northern hemisphere sky. An orange hypergiant with the solar radii of 1535, RW Cephei is 11,400 lights years away from Earth’s surface.
Where is the real sun
The sun lies at the heart of the solar system, where it is by far the largest object. It holds 99.8% of the solar system’s mass and is roughly 109 times the diameter of the Earth — about one million Earths could fit inside the sun.

More than 80% of the stars in our galaxy are cool, less massive “red dwarf” stars. The Sun is by no means typical in the sense of common!
How common are stars like our sun

What is the coolest star in the universe

What star is the hottest
That’s even hotter. But the hottest known stars in the Universe are the blue hypergiant stars. These are stars with more than 100 times the mass of the Sun. One of the best known examples is Eta Carinae, located about 7,500 light-years from the Sun.
What’s bigger than the sun
Betelgeuse, a red giant, is about 700 times bigger than the sun and about 14,000 times brighter. “We have found stars that are 100 times bigger in diameter than our sun. Truly those stars are enormous,” NASA says on its SpacePlace website.
Is the sun White
The color of the sun is white. The sun emits all colors of the rainbow more or less evenly and in physics, we call this combination “white”. That is why we can see so many different colors in the natural world under the illumination of sunlight.
