Alpha Camelopardalis - HD30614 - HIP22783

Alpha Camelopardalis is a blue very luminous supergiant star that can be located in the constellation of Camelopardalis. Alpha Camelopardalis is the Bayer Classification for the star. HIP22783 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD30614. Alpha Camelopardalis has alternative name(s), 9 Camelopardalis , 9 Cam.

Location of Alpha Camelopardalis

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 Alpha Camelopardalis, the location is 04h 54m 03.01 and +66d20`33.6 .

Proper Motion of Alpha Camelopardalis

All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun. In the case of a star, its the galactic centre. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. Proper Motion details the movements of these stars and are measured in milliarcseconds. The star is moving 006.89 ± 000.14 towards the north and -000.13 ± 000.19 east if we saw them in the horizon.

Physical Properties (Colour, Temperature, Radius) of Alpha Camelopardalis

Alpha Camelopardalis has a spectral type of O9.5Ia SB:. This means the star is a blue supergiant star. The star has a B-V Colour Index of 0 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 10,293 Kelvin.

Alpha Camelopardalis has been calculated as 87.88 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 61,147,166.64.km.

Alpha Camelopardalis Apparent and Absolute Magnitudes

Alpha Camelopardalis has an apparent magnitude of 4.26 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 -7.38 If you used the 2007 Parallax value, you would get an absolute magnitude of -7.16. 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 Alpha Camelopardalis

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 0.47 which gave the calculated distance to Alpha Camelopardalis as 6939.65 light years away from Earth or 2127.66 parsecs. It would take a spaceship travelling at the speed of light, 6939.65 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

In 2007, Hipparcos data was revised with a new parallax of 0.52 which put Alpha Camelopardalis at a distance of 6272.37 light years or 1923.08 parsecs. It should not be taken as though the star is moving closer or further away from us. It is purely that the distance was recalculated. Alpha Camelopardalis brightness ranges from a magnitude of 4.000 to a magnitude of 4.000 over its variable period. The smaller the magnitude, the brighter the star.

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 Stellar Age, Metallicity or Mass is from the E.U. Exoplanets. The information was obtained as of 12th Feb 2017.
