Location of HR 6392

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 HR 6392, the location is 17h 14m 27.66 and -39° 45` 59.9 .

Physical Properties (Colour, Temperature, Radius) of HR 6392

HR 6392 Colour and Temperature

HR 6392 has a spectral type of K0Ia. This means the star is a orange to red supergiant star. The star has a B-V Colour Index of 2.28 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 327 Kelvin.

HR 6392 Radius

HR 6392 has been calculated as 760.00 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 528,808,000.00.km. If you need the diameter of the star, you just need to multiple the radius by 2.

HR 6392 Apparent and Absolute Magnitudes

HR 6392 has an apparent magnitude of 6.42 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 HR 6392

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as -0.60 which gave the calculated distance to HR 6392 as -5436.06 light years away from Earth or -1666.67 parsecs. It would take a spaceship travelling at the speed of light, -5436.06 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

Variable Type of HR 6392

The star is a pulsating Slow Irregular variable type which means that its size changes over time. The Variable Type is usually named after the first star of that type to be spotted. HR 6392 brightness ranges from a magnitude of 6.497 to a magnitude of 6.298 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 0.2 days (variability).

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.
