Difference between Sigma Draconis and Stellar classification

Sigma Draconis vs. Stellar classification

Sigma Draconis (σ Draconis, abbreviated Sig Dra, σ Dra), also named Alsafi, is a 4.7-magnitude star located at a distance of 18.8 light-years from the Sun in the constellation of Draco. In astronomy, stellar classification is the classification of stars based on their spectral characteristics.
