HIP 25304, HD35237

HIP 25304 is a orange to red star that can be located in the constellation of Auriga. 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 25304's Alternative Names

HIP25304 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD35237.

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+32 973.

Location of HIP 25304

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 25304, the location is 05h 24m 46.68 and +32° 42` 27.9 .

Physical Properties (Colour, Temperature) of HIP 25304

HIP 25304 has a spectral type of K0. This means the star is a orange to red star. The star has a B-V Colour Index of 1.14 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 4,683 Kelvin.

HIP 25304 Radius has been calculated as being 17.61 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 12,255,869.53.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 25304 Apparent and Absolute Magnitudes

HIP 25304 has an apparent magnitude of 8.72 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 -0.47 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 25304

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 1.45 which gave the calculated distance to HIP 25304 as 2249.40 light years away from Earth or 689.66 parsecs. It would take a spaceship travelling at the speed of light, 2249.40 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.
