HIP64737 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD115071.
V961 Centauri has alternative name(s) :- V961 Cen, V961 Cen.
More details on objects' alternative names can be found at Star Names .
The location of the main sequence 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 V961 Centauri, the location is 13h 16m 04.81 and -62° 35` 01.5 .
V961 Centauri has a spectral type of O9.5V. This means the star is a blue main sequence star. The star has a B-V Colour Index of 0.22 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 7,650 Kelvin.
V961 Centauri has an apparent magnitude of 7.95 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 -0.63 which gave the calculated distance to V961 Centauri as -5177.20 light years away from Earth or -1587.30 parsecs. It would take a spaceship travelling at the speed of light, -5177.20 years to get there. We don't have the technology or spaceship that can carry people over that distance yet. V961 Centauri brightness ranges from a magnitude of 8.074 to a magnitude of 7.987 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 1.4 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.
