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 object is compared to the celestial equator and is expressed in degrees. For Qatar-2, the location is 13h 50m 37.00 and -06° 48` 14.00 .
Qatar-2 has a spectral type of K. This means the star is a orange to red star.
Qatar-2 has been calculated as 0.71 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 496,105.40.km. If you need the diameter of the star, you just need to multiple the radius by 2.
Qatar-2 has an apparent magnitude of 13.30 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. 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.
