Is Capella a main sequence star?

Answer 1

Yes, but technically Capella isn't just no because it is actually a star system consisting of 4 stars in 2 binary pairs. For the first pair they are type-G GIANT stars, with a radius 10x the Sun's in a close orbit around each other, they are thought to be cooling by many astronomers and are on their path to becoming a red giant. The second pair are small, cool (compared to other stars), red dwarfs. The two pairs are about 10,000 astronomical units apart (1,500,000 km./930,000 mi.).

Answer 2

Capella is the brightest star in the constellation Auriga.

To the visual eye, it looks like a single star, but is in fact 4 stars comprised of two binary pairs.

The first pair are a set of G-type stars (Like our Sun) that are coming to the end of their lives.

The second pair are a set of red dwarfs.

All four are still on the main sequence.

Answer 3

Yes, Capella is a main sequence star. It is a class G giant star, located in the constellation Auriga, and it is one of the brightest stars in the sky.
