The location of the multiple star system 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 Algieba B, the location is 18h 15m 40.06 and +51 ° 37` 45.0 .
Algieba B has a spectral type of K0. This means the star is a orange to red multiple star system. The star has a B-V Colour Index of 0.69 which means the star's temperature is about 5,671 Kelvin. The temperature was calculated using information from Morgans @ Uni.edu at being .
Algieba B has an apparent magnitude of 8.26 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.
