V486 Cas is a blue eclipsing binary system giant star that can be located in the constellation of Cassiopeia. The star can not be seen by the naked eye, you need a telescope to see it.
HIP3346 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD3950.
V486 Cas has alternative name(s), V486_Cas.
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 V486 Cas, the location is 00h 42m 37.99 and +52d20`13.8 .
V486 Cas has a spectral type of B1III. This means the star is a blue giant star. The star has a B-V Colour Index of 0.05 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 8,917 Kelvin.
V486 Cas Radius has been calculated as being 72.87 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 50,700,546.23.km. The figure is derived at by using the formula from SDSS and has been known to produce widely incorrect figures.
V486 Cas has an apparent magnitude of 6.94 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 -6.35 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.
Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 0.22 which gave the calculated distance to V486 Cas as 14825.61 light years away from Earth or 4545.45 parsecs. It would take a spaceship travelling at the speed of light, 14825.61 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.
The star is a eclipsing binary system Eclipsing 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. V486 Cas brightness ranges from a magnitude of 7.000 to a magnitude of 7.000 over its variable period. The smaller the magnitude, the brighter the star.
