HIP32776 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD49676.
QV Geminorum has alternative name(s) :- , QV Gem.
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+12 1310.

The location of the variable 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 QV Geminorum, the location is 06h 50m 02.18 and +12° 03` 29.3 .
Based on the star's spectral type of M... , QV Geminorum's colour and type is red variable star. The star has a B-V Colour Index of 1.8 which means the star's temperature is about 3,025 Kelvin. The temperature was calculated using information from Morgans @ Uni.edu.
QV Geminorum has an apparent magnitude of 6.85 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.
Using the original Hipparcos data that was released in 1997, the parallax to the star was given as -0.36000 which gave the calculated distance to QV Geminorum as -9060.09 light years away from Earth or -2777.78 parsecs. If you want that in miles, it is about -53,260,874,957,327,093.12, based on 1 Ly = 5,878,625,373,183.61 miles.
QV Geminorum brightness ranges from a magnitude of 6.917 to a magnitude of 6.833 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 0.1 days (variability).
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.
