HIP 6462, HD8379

HIP 6462 is a blue to white star that can be located in the constellation of Pisces. 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 6462's Alternative Names

HIP6462 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD8379.

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+08 218.

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

Location of HIP 6462

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 6462, the location is 01h 23m 06.78 and +09° 11` 15.8 .

Proper Motion of HIP 6462

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 -42.95 ± 0.41 miliarcseconds/year towards the north and 36.96 ± 0.58 miliarcseconds/year east if we saw them in the horizon.

HIP 6462 Luminosity

Luminosity is the amount of energy that a star pumps out and its relative to the amount that our star, the Sun gives out. The figure of 10.75 that I have given is based on the value in the Simbad Hipparcos Extended Catalogue at the University of Strasbourg from 2012.

Physical Properties (Colour, Temperature) of HIP 6462

HIP 6462 has a spectral type of F0. This means the star is a blue to white star. The star is 7,448.00 Parsecs from the Galactic Centre or terms of Light Years is 24,292.65 s. The star has a B-V Colour Index of 0.32 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 6,698 Kelvin.

HIP 6462 Radius has been calculated as being 2.26 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 1,575,700.55.km. If you need the diameter of the star, you just need to multiple the radius by 2. However with the 2007 release of updated Hipparcos files, the radius is now calculated at being round 2.51. The figure is derived at by using the formula from SDSS and has been known to produce widely incorrect figures.

HIP 6462 Apparent and Absolute Magnitudes

HIP 6462 has an apparent magnitude of 7.43 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 2.43 If you used the 2007 Parallax value, you would get an absolute magnitude of 2.21. 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 6462

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 10.01 which gave the calculated distance to HIP 6462 as 325.84 light years away from Earth or 99.90 parsecs. It would take a spaceship travelling at the speed of light, 325.84 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 9.03 which put HIP 6462 at a distance of 361.20 light years or 110.74 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.

The star's Galacto-Centric Distance is 7,448.00 Parsecs or 24,292.65 Light Years. The Galacto-Centric Distance is the distance from the star to the Centre of the Galaxy which is Sagittarius A*.

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.
