spektrityypin
Spektrityypin is a term that refers to the spectral type of a star. This classification system categorizes stars based on their surface temperature and spectral characteristics. The most common spectral classification scheme is the Morgan-Keenan (MK) system, which uses letters O, B, A, F, G, K, and M, ordered from hottest to coolest. Each letter is further subdivided into numbers from 0 to 9, indicating finer temperature variations. For instance, a G2 star like our Sun is cooler than a G0 star.
Beyond temperature, spectral types also reveal information about a star's chemical composition and luminosity class. The
