16 Sagittarii's Alternative Names

The Id of the star in the Yale Bright Star Catalogue is HR6823. HIP89440 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD167263.

Flamsteed designations are named after the creator, Sir John Flamsteed. Sir John named the stars in the constellation with a number and its latin name, this star's Flamsteed designation is 16 Sagittarii. The Flamsteed name can be shortened to 16 Sgr.

The Gould star designation is one that was designed by American astronomer, Benjamin Apthorp Gould. Gould stars are predominantly in the Southern and Equatorial constellations but do appear in northern constellations such as Bootes and Orion. The star has the designation 44 G. Sagittarii. There are no stars with a Gould designation in Ursa Major for example.

BD number is the number that the star was filed under in the Durchmusterung or Bonner Durchmusterung, a star catalogue that was put together by the Bonn Observatory between 1859 to 1903. The star's BD Number is BD-20 5055.

Location of 16 Sagittarii

The location of the supergiant star in the night sky is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. If the R.A. is positive then its eastwards. The Declination is how far north or south the object is compared to the celestial equator and is expressed in degrees. For 16 Sagittarii, the location is 18h 15m 12.97 and -20 ° 23` 16.7 .

Physical Properties of 16 Sagittarii

16 Sagittarii Temperature and Colour

Based on the star's spectral type of B0.5Ib/II , 16 Sagittarii's colour and type is blue supergiant star. The star has a B-V Colour Index of -0.02 which means the star's temperature is about 10,827 Kelvin. The temperature was calculated using information from Morgans @ Uni.edu.

16 Sagittarii Radius

16 Sagittarii Apparent and Absolute Magnitudes

16 Sagittarii has an apparent magnitude of 5.96 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Using the supplied Parallax value, you would get an absolute magnitude of Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.

Distance to 16 Sagittarii

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 0.00000 which gave the calculated distance to 16 Sagittarii as 0 light years away from Earth or 0 parsecs. If you want that in miles, it is about 0.00, based on 1 Ly = 5,878,625,373,183.61 miles.

Source of Information

The source of the information if it has a Hip I.D. is from Simbad, the Hipparcos data library based at the University at Strasbourg, France. Hipparcos was a E.S.A. satellite operation launched in 1989 for four years. The items in red are values that I've calculated so they could well be wrong. Information regarding Metallicity and/or Mass is from the E.U. Exoplanets. The information was obtained as of 12th Feb 2017.

Multi-Star System

The star has been identified as being a multi-star system, one in which there is at least one star in close orbit to another star or two or more stars orbiting a central point. The stars may be of equal mass, unequal mass where one star is stronger than the other or be in groups orbiting a central point which doesn't necessarily have to be a star. More information can be found on my dedicated multiple star systems page. The source of the info is Simbad. The file is dated 2000 so any differences between this and any other source will be down to the actual source from where the information came from.
