Is Mirach a red giant?

Mirach, also known as Beta Andromedae, is a moderately bright star in the constellation Andromeda. It’s what’s known as a red giant star, in the final stages of its evolution, a star whose outer layers have expanded.

Is alpheratz a blue giant?

Alpheratz is a binary star with an apparent magnitude of +2.06. It is a hot blue star classified as a B8 subgiant. The brighter of the two stars in the binary system has an unusual chemical composition, with unusually high levels of mercury, manganese, and other elements.

Is alpheratz bigger than the sun?

Distance, Size, and Mass The primary star designated as Alpheratz A has around 3.8 solar masses, or 380% of our Sun’s mass, and 2.7 solar radii, or 270% of our Sun’s radius. It is thus more than 5 times bigger than our Sun. It is three times bigger than our Sun.

Is Mirach a single star?

It’s what’s known as a red giant star, in the final stages of its evolution, a star whose outer layers have expanded. But Mirach is rather far away at 197 light-years, and thus it shines in our sky at only 2nd magnitude, a respectable brightness but not as bright as many other stars.

What constellation is the north star in?

What kind of star is the star Mirach?

Mirach is a familiar star to stargazers because it is commonly used to find two bright galaxies, the Andromeda Galaxy(Messier 31) and the Triangulum Galaxy(Messier 33). The Andromeda Galaxy lies 8 degrees northwest of Mirach, while Triangulum appears 7 degrees southwest of the star.

What’s the difference between Alpheratz and Mirach star?

But their constellation and apparent brightness is about all they have in common. Alpheratz is a hot, blue (class B) star, whereas Mirach is a cool red class M (M0) giant (the color difference notable to the eye), and quite a bright giant at that. Mirach’s name is something of a mistake.

How big is Mirach compared to the Sun?

Mirach is a red giant star of the spectral type M0 III. It has a mass 3 to 4 times that of the Sun and has expanded to a size of 100 solar radii. If it were placed at the centre of our solar system, the star would extend to the orbit of Mercury. With an effective temperature of 3,842 K, it is 1,995 times more luminous than the Sun.

What is the iron abundance of Mirach star?

Mirach Iron Abundance is -0.03 with an error value of 9.99 Fe/H with the Sun has a value of 1 to put it into context. The value comes from the Hipparcos Extended Catalog. Mirach has an apparent magnitude of 2.07 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude.
