HD 122675's star type is giant star that can be located in the constellation of Canes Venatici. The description is based on the spectral class.
Based on the spectral type (K2III) of the star, the star's colour is orange to red .
HIP68567 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD122675.
The location of the giant 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 object is compared to the celestial equator and is expressed in degrees. For HD 122675, the location is 14h 02m 12.17 and +45° 45` 13.1 .
The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is -50.23 km/s with an error of about 0.21 km/s . When the value is negative then the star and the Sun are getting closer to one another, likewise, a positive number means that two stars are moving away. Its nothing to fear as the stars are so far apart, they won't collide in our life-time, if ever.
Physical Properties (Colour, Temperature) of HD 122675
HD 122675 has a spectral type of K2III. This means the star is a orange to red giant star. The star has a B-V Colour Index of 1.35 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 4,241 Kelvin.
Radius has been calculated as being 15.99 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 11,128,832.77.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 16.29. The figure is derived at by using the formula from SDSS and has been known to produce widely incorrect figures.
Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 5.99 which gave the calculated distance to HD 122675 as 544.51 light years away from Earth or 166.94 parsecs. It would take a spaceship travelling at the speed of light, 544.51 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 5.88 which put HD 122675 at a distance of 554.70 light years or 170.07 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.
