What type of star is Sigma Scorpii?
The primary component of the spectroscopic binary, Sigma Scorpii Aa1, is an evolved giant star with a stellar classification of B1 III. It has around 18 times the mass of the Sun and 12 times the Sun’s radius.
What color is the star Sigma?
Colour and Temperature Based on the star’s spectral type of B9Vvar , Sigma Herculis’s colour and type is blue main sequence star. Based on the spectral type, we can deduce that the surface temperature of the star is in the order of between 10,000 and 25,000K based on the notes from Harvard University.
How far is Alniyat from Earth?

What type of star is 40 Eri B?
A-type star
The star in question is 40 Eridani B, which is part of triple stellar system in the Sun’s neighbourhood, only 5.0 parsec away from us. It was classified as an A-type star by Williamina Fleming, one of the women computers working at the Harvard College Observatory.
Is Nunki a red giant?
Nunki is a hydrogen-fusing dwarf with a mass 7.8 times that of the Sun and a radius 4.5 times solar. It is 3,300 times more luminous than the Sun, with a surface temperature of 18,890 K. At the end of its life cycle, it will turn into a white dwarf with a mass comparable to that of the Sun.
Is Shaula a red giant?

Is yed prior a red giant?
Epsilon Ophiuchi or ε Ophiuchi, formally named Yed Posterior (/ˌjɛd pɒˈstɪəriər/), is a red giant star in the constellation of Ophiuchus. Located less than five degrees south of the celestial equator in the eastern part of the constellation, it forms a naked eye optical double with Delta Ophiuchi (named Yed Prior).
Is the star Alniyat in the constellation Scorpius?
Alniyat is a B1III giant star based on the spectral type that was recorded in the Hipparcos star catalogue. Alniyat is a main star in the constellation Scorpius and makes up the constellation outline. Based on the spectral type (B1III) of the star, the star’s colour is blue.
How big is the star Al Niyat in magnitude?
Rather well down the Greek alphabet, Al Niyat, a mid-third magnitude star (2.89), ranks eighth in the constellation. In line with its “double name” Al Niyat (Sigma) is not only double, but is at least quadruple!
How big is Alniyat compared to the Earth?
Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 4.44000 which gave the calculated distance to Alniyat as 734.60 light years away from Earth or 225.23 parsecs. If you want that in miles, it is about 4,318,438,199,140,679.91, based on 1 Ly = 5,878,625,373,183.61 miles.
Where does the name Al Niyat come from?
The name, which comes directly from an Arabic word that means “the arteries” (to the Arabic view of Antares as the heart) applies to both Sigma Scorpii and to the lower of the two stars, Tau Scorpii, and can be used for either. Rather well down the Greek alphabet, Al Niyat, a mid-third magnitude star (2.89), ranks eighth in the constellation.
