VZ Volantis, HD54733, HIP34126

VZ Volantis is a red giant star that can be located in the constellation of Volans. The description is based on the spectral class. The star can not be seen by the naked eye, you need a telescope to see it.

VZ Volantis's Alternative Names

HIP34126 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD54733.

VZ Volantis has alternative name(s) :- , VZ Vol.

More details on star alternative names can be found at Star Names .

Location of VZ Volantis

The location of the 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 star is compared to the celestial equator and is expressed in degrees. For VZ Volantis, the location is 07h 04m 35.13 and -68° 14` 54.9 .

Proper Motion of VZ Volantis

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 11.21 ± 0.50 miliarcseconds/year towards the north and -16.27 ± 0.56 miliarcseconds/year east if we saw them in the horizon.

Physical Properties (Colour, Temperature) of VZ Volantis

VZ Volantis has a spectral type of M5III. This means the star is a red giant star. The star has a B-V Colour Index of 1.5 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 3,989 Kelvin.

VZ Volantis Radius has been calculated as being 21.64 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 15,054,346.83.km. If you need the diameter of the star, you just need to multiple the radius by 2. However with the 2007 release of updated Hipparcos files, the radius is now calculated at being round 24.61. The figure is derived at by using the formula from SDSS and has been known to produce widely incorrect figures.

VZ Volantis Apparent and Absolute Magnitudes

VZ Volantis has an apparent magnitude of 8.31 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 -0.22 If you used the 2007 Parallax value, you would get an absolute magnitude of -0.50. 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 VZ Volantis

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 1.97 which gave the calculated distance to VZ Volantis as 1655.65 light years away from Earth or 507.61 parsecs. It would take a spaceship travelling at the speed of light, 1655.65 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 1.73 which put VZ Volantis at a distance of 1885.34 light years or 578.03 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. VZ Volantis brightness ranges from a magnitude of 8.337 to a magnitude of 8.214 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 0.1 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.
