14 Arietis is a blue to white giant star that can be located in the constellation of Aries. 14 Arietis is the brightest star in Aries based on the Hipparcos 2007 apparent magnitude. The star can be seen with the naked eye, that is, you don't need a telescope/binoculars to see it.
The Id of the star in the Yale Bright Star Catalogue is HR623. HIP10053 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD13174.
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 14 Arietis, the location is 02h 09m 25.29 and +25d 56` 23.9 .
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 -34.99 ± 0.63 miliarcseconds/year towards the north and 70.46 ± 1.07 miliarcseconds/year east if we saw them in the horizon.
14 Arietis has a spectral type of F2III. This means the star is a blue to white giant star. The star is 7466.00000000 Parsecs from the Galactic Centre or terms of Light Years is 24351.3552630400000000s. The star has a B-V Colour Index of 0.33 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 7,066 Kelvin.
14 Arietis Radius has been calculated as being 6.17 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 4,295,763.54.km. However with the 2007 release of updated Hipparcos files, the radius is now calculated at being round 5.55. The figure is derived at by using the formula from SDSS and has been known to produce widely incorrect figures.
14 Arietis has an apparent magnitude of 4.98 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 0.02 If you used the 2007 Parallax value, you would get an absolute magnitude of 0.25. 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.
Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 10.19 which gave the calculated distance to 14 Arietis as 320.08 light years away from Earth or 98.14 parsecs. It would take a spaceship travelling at the speed of light, 320.08 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 11.30 which put 14 Arietis at a distance of 288.64 light years or 88.50 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 7,466.00 Parsecs or 24,351.36 Light Years. The Galacto-Centric Distance is the distance from the star to the Centre of the Galaxy which is Sagittarius A*.
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.

The star has been identified as being a multi-star system, one in which there is at least one star in close orbit to another star or two or more stars orbiting a central point. The stars may be of equal mass, unequal mass where one star is stronger than the other or be in groups orbiting a central point which doesn't necessarily have to be a star. More information can be found on my dedicated multiple star systems page. The source of the info is Simbad. The file is dated 2000 so any differences between this and any other source will be down to the actual source from where the information came from.
