HD 46966 Facts

HD 46966's Alternative Names

HIP31567 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD46966.

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+06 1303.

More details on objects' alternative names can be found at Star Names .

Location of HD 46966

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 object is compared to the celestial equator and is expressed in degrees. For HD 46966, the location is 06h 36m 25.89 and +06 ° 04` 59.5 .

Physical Properties (Colour, Temperature) of HD 46966

HD 46966 Colour and Temperature

HD 46966 has a spectral type of O8. This means the star is a blue - white star. The star has a B-V Colour Index of -0.06 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 12,136 Kelvin.

HD 46966 Apparent and Absolute Magnitudes

HD 46966 has an apparent magnitude of 6.87 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 HD 46966

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as -1.00 which gave the calculated distance to HD 46966 as 0 light years away from Earth or 0 parsecs. If you want that in miles, it is 0.

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.
