HIP 6632, HD8493

HIP 6632 is a blue star that can be located in the constellation of Cassiopeia. The description is based on the spectral class. The star can not be seen by the naked eye, you need a telescope to see it.

HIP 6632's Alternative Names

HIP6632 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD8493.

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+53 297.

Location of HIP 6632

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 HIP 6632, the location is 01h 25m 05.97 and +54° 23` 26.6 .

Physical Properties (Colour, Temperature) of HIP 6632

HIP 6632 has a spectral type of A. This means the star is a blue star. The star has a B-V Colour Index of 0.26 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 6,999 Kelvin.

HIP 6632 Radius has been calculated as being 30.40 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 21,151,892.12.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.

HIP 6632 Apparent and Absolute Magnitudes

HIP 6632 has an apparent magnitude of 9.29 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 -3.40 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 HIP 6632

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 0.29 which gave the calculated distance to HIP 6632 as 11247.01 light years away from Earth or 3448.28 parsecs. It would take a spaceship travelling at the speed of light, 11247.01 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

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.
