VV Cassiopeiae Facts

VV Cassiopeiae's Alternative Names

HIP8614 is the reference name for the star in the Hipparcos Star Catalogue.

VV Cassiopeiae has alternative name(s) :- VV Cas, VV Cas.

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+59 335.

Location of VV Cassiopeiae

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 VV Cassiopeiae, the location is 01h 51m 07.02 and +59° 53` 17.6 .

Physical Properties (Colour, Temperature) of VV Cassiopeiae

VV Cassiopeiae Colour and Temperature

VV Cassiopeiae has a spectral type of F9Ib. This means the star is a blue to white supergiant star. The star has a B-V Colour Index of 0.96 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 5,060 Kelvin.

VV Cassiopeiae Apparent and Absolute Magnitudes

VV Cassiopeiae has an apparent magnitude of 10.59 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 VV Cassiopeiae

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as -4.78 which gave the calculated distance to VV Cassiopeiae as -682.35 light years away from Earth or -209.21 parsecs. It would take a spaceship travelling at the speed of light, -682.35 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

Variable Type of VV Cassiopeiae

The star is a pulsating Delta Cepheid 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. VV Cassiopeiae brightness ranges from a magnitude of 11.358 to a magnitude of 10.440 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 6.2 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.
