Caption: A Hertzsprung-Russell (HR) diagram with some well known named stars (i.e., stars with traditional names) of the Milky Way and some translations to Swahili.
Features:
The temperature scales increases to the left by a senseless astronomy convention.
The spectral types are from the OBAFGKM stellar classification system---mnemonicked by "O be a fine girl/guy kiss me."
The spectral types are subdivided into spectral subtypes labeled by numbers running 0 through 9 going in photosphere temperature. The spectral subtypes labels are NOT shown on the HR diagram.
The main sequence phase of a star's nuclear burning lifetime is the longest phase, and so most nuclear burning stars are main-sequence stars.
