What does the spectral class letters mean?
The spectral class letters in astronomy represent the temperature and color of stars. The sequence starts with O (hottest and bluest stars) and ends with M (coolest and reddest stars). The spectral class letters are O, B, A, F, G, K, and M.
Is spectral class B in space hot or cold?
Spectral class is the categorization of stars by temperature and size, mostly the former. Spectral class B is very hot. In descending order (hottest to coolest) the spectral classes are O,B,A,F,G,K,M. You can see that B is very near the top.
