13 Lacertae is an orange to red giant star that can be located in the constellation of Lacerta. HIP is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD. 13 Lacertae has alternative name(s), 13 Lacertae.
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 from celestial equator. The Declination is how up or down compared to the celestial equator and is expressed in degrees. For 13 Lacertae, the location is 22h 44m 05.49 and +41 d 49 ` 09.2 .
13 Lacertae has a spectral type of K0III. This means the star is (K) orange to red coloured (III) giant. 13 Lacertae lies at a distance of 274.32 light years away from our Sun and our planet Earth or to put it another way, 84.01 parsecs away from the Sun.
13 Lacertae has an apparent magnitude of 5.11 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. 13 Lacertae has an absolute magnitude of 0.49 which is the apparent magnitude of an object if it were 32.6 light years away or 10 parsecs from Earth. 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. The stars temperature has been calculated at between 3700 and 5200 based on the Class Type and lookup at Wikipedia-Stellar Classification
