HIP 25264, HD243252

HIP 25264 is a blue to white star that can be located in the constellation of Taurus. 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 25264's Alternative Names

HIP25264 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD243252.

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+22 890.

Location of HIP 25264

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 25264, the location is 05h 24m 12.33 and +22° 08` 25.2 .

Proper Motion of HIP 25264

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 -14.91 ± 2.15 miliarcseconds/year towards the north and 14.83 ± 4.23 miliarcseconds/year east if we saw them in the horizon.

Physical Properties (Colour, Temperature) of HIP 25264

HIP 25264 has a spectral type of F2. This means the star is a blue to white star. The star has a B-V Colour Index of 0.72 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 5,603 Kelvin.

HIP 25264 Apparent and Absolute Magnitudes

HIP 25264 has an apparent magnitude of 10.00 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 If you used the 2007 Parallax value, you would get an absolute magnitude of 2.66. 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 25264

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as -0.93 which gave the calculated distance to HIP 25264 as -3507.13 light years away from Earth or -1075.27 parsecs. It would take a spaceship travelling at the speed of light, -3507.13 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 3.40 which put HIP 25264 at a distance of 959.30 light years or 294.12 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.

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.
