A yellow star. The Sun is definitely not a red giant; if it were to swell to the size of a red giant (like Antares, for example), our Earth would end up inside the Sun.
Dubhe is not a red giant but rather a subgiant star. It is the brightest star in the Big Dipper asterism and is classified as an evolved F-type subgiant star.
No, Betelgeuse is a red giant.
Most yellow stars do. The Sun is expected to follow this progression.
No. The sun is a yellow main sequence star, sometimes called a yellow dwarf. The term is a bit counterintuitive, as a yellow dwarf is a bit larger than the average star, but still far smaller than a red giant.
Let's see...the life sequence for a YELLOW DWARF star, like our little G2, will see it become a red giant in a few billion years, probably consuming everything out to the orbit of Earth and not doing any favors to what's left of the solar system. So, in a way, its a red giant in the making. But its too small to ever be a neutron star. So, its a yellow star today, but someday will be a red giant. That's 3, maybe 4 billion years from now, so the yellow star will still be there for a very long time to come.
A red giant star.
Red giant is a type of star.
the steps in the life of a star is the yellow dwarf,red giant,white dwarf & the black dwarf.
The number would vary greatly, as reg giants vary in size, but a sunlike star may become a red giant of about 200 solar radii. A star that size would have about 10 trillion times the volume of Earth.
If the question was what is the biggest star in the universe it would be Canis Majoris, which is HUGE. We can fit 1 million Earths inside our sun, and you can fit 7 QUADRILLION Earths inside Canis Majoris!
Capella is a binary star system located in the constellation of Auriga. It consists of two giant stars, Capella A and Capella B. Capella A is a yellow giant star, while Capella B is a smaller, cooler red giant star.
