The two stars are separated by 0.36° in the sky and are 378 light years from earth. The combined mass of the binary pair is 5.26 ± 0.37 times the mass of the Sun and their blended stellar classification is A2.5 Va. The black hole at the centre of the Milky Way lies at a distance of 26,000 light years from Earth.

If you want that in miles, it is about 707,786,494,931,306.64, based on 1 Ly = 5,878,625,373,183.61 miles.

It is the third brightest star in the constellation, after Epsilon and Sigma Sagittarii. The star is approximately 89.1 light years distant from Earth. Beta Sagittarii, located at a position associated with the forelegs of the centaur, has the traditional name The Bayer designation Beta Sagittarii (Beta Sgr, β Sagittarii, β Sgr) is shared by two star systems, β¹ Sagittarii, with apparent magnitude 3.96, and β² Sagittarii, magnitude 7.4. Sagittarius A* (pronounced “Sagittarius A-star”) is the most plausible candidate for the location of the supermassive black hole at the centre of our galaxy.

It is the constellation’s third brightest star, after Kaus Australis and Nunki.The system has a combined apparent magnitude of 2.59 and lies at a distance of 88 light years from Earth.

Also known as Zeta Sagittarii, Ascella is a binary star system around 90 light years from Earth, both stars are white giants orbiting each other every 21 years. Now turn your attention towards Epsilon Sagittarii – the backwards “3” symbol on our chart. Its traditional name, Ascella, means “armpit” in Latin. It is a spectral type F2 giant star, but much closer at 137 light years in distance. Ascella, Zeta Sagittarii (ζ Sgr), is a multiple star system located in the constellation Sagittarius. The two components Zeta Sagittarii A and B orbit each other over a period of 21 years at an eccentricity of 0.211.

Ascella – ζ Sagittarii (Zeta Sagittarii) Zeta Sagittarii is another binary star in Sagittarius.
If you want that in miles, it is about 523,726,734,496,927.81, based on 1 Ly = 5,878,625,373,183.61 miles. Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 27.09000 which gave the calculated distance to Tau Sagittarii as 120.40 light years away from Earth or 36.91 parsecs.

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 36.61000 which gave the calculated distance to Ascella as 89.09 light years away from Earth or 27.31 parsecs.
