VY Canum Venaticorum, HIP65913

VY Canum Venaticorum is a red pulsating variable star that can be located in the constellation of Canes Venatici. The description is based on the spectral class. VY Canum Venaticorum is not part of the constellation but is within the borders of the constellation.

The star can not be seen by the naked eye, you need a telescope to see it.

VY Canum Venaticorum's Alternative Names

HIP65913 is the reference name for the star in the Hipparcos Star Catalogue.

VY Canum Venaticorum has alternative name(s) :- , VY CVn.

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+38 2454.

Location of VY Canum Venaticorum

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 VY Canum Venaticorum, the location is 13h 30m 43.93 and +37° 46` 30.0 .

Physical Properties (Colour, Temperature) of VY Canum Venaticorum

VY Canum Venaticorum has a spectral type of M5. This means the star is a red variable star. The star has a B-V Colour Index of 1.49 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 4,035 Kelvin.

VY Canum Venaticorum Radius has been calculated as being 43.37 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 30,179,929.94.km. If you need the diameter of the star, you just need to multiple the radius by 2. The figure is derived at by using the formula from SDSS and has been known to produce widely incorrect figures.

VY Canum Venaticorum Apparent and Absolute Magnitudes

VY Canum Venaticorum has an apparent magnitude of 8.96 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 -1.78 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 VY Canum Venaticorum

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 0.71 which gave the calculated distance to VY Canum Venaticorum as 4593.85 light years away from Earth or 1408.45 parsecs. It would take a spaceship travelling at the speed of light, 4593.85 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

Variable Type of VY Canum Venaticorum

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. VY Canum Venaticorum brightness ranges from a magnitude of 9.312 to a magnitude of 8.812 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 0.5 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.
