Beta Phoenicis, HD6595, HIP5165, HR322

Beta Phoenicis is a white to yellow giant star that can be located in the constellation of Phoenix. The star can be seen with the naked eye, that is, you don't need a telescope/binoculars to see it.

Beta Phoenicis's Alternative Names

Beta Phoenicis is the Bayer Classification for the star. The Id of the star in the Yale Bright Star Catalogue is HR322. HIP5165 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD6595.

Beta Phoenicis has alternative name(s) :- Beta Phoenicis .

Location of Beta Phoenicis

The location of the star in the galaxy 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 star is compared to the celestial equator and is expressed in degrees. For Beta Phoenicis, the location is 01h 06m 05.11 and -46° 43` 06.6 .

Proper Motion of Beta Phoenicis

All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun. In the case of a star, its the galactic centre. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. Proper Motion details the movements of these stars and are measured in milliarcseconds. The star is moving 34.97 ± 8.86 miliarcseconds/year towards the north and -80.81 ± 14.62 miliarcseconds/year east if we saw them in the horizon. The Radial Velocity, that is the speed at which the star is moving away/towards us is -1.10000 km/s with an error of about 0.74 km/s .

Physical Properties (Colour, Temperature) of Beta Phoenicis

Beta Phoenicis has a spectral type of G8IIIvar. This means the star is a white to yellow giant star. The star has a B-V Colour Index of 0.8 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 5,286 Kelvin.

Beta Phoenicis Radius has been calculated as being 14.68 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 10,212,672.45.km. However with the 2007 release of updated Hipparcos files, the radius is now calculated at being round 2007.98. The figure is derived at by using the formula from SDSS and has been known to produce widely incorrect figures.

Beta Phoenicis Apparent and Absolute Magnitudes

Beta Phoenicis has an apparent magnitude of 3.32 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. If you used the 1997 Parallax value, you would get an absolute magnitude of -0.60 If you used the 2007 Parallax value, you would get an absolute magnitude of -11.28. 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 Beta Phoenicis

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 16.46 which gave the calculated distance to Beta Phoenicis as 198.16 light years away from Earth or 60.75 parsecs. It would take a spaceship travelling at the speed of light, 198.16 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

In 2007, Hipparcos data was revised with a new parallax of 0.12 which put Beta Phoenicis at a distance of 27180.28 light years or 8333.33 parsecs. It should not be taken as though the star is moving closer or further away from us. It is purely that the distance was recalculated.

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.
