What is spectral class?
Spectral class is a classification system for stars based on their temperature and spectral characteristics. It categorizes stars into different groups, such as O, B, A, F, G, K, and M, with O being the hottest and M being the coolest. Spectral class is indicated by a letter, with additional subtype information denoted by a number.
Of the spectral classes the highest temperature class is designated as what?
The O spectral class is the highest temperature class. Stars in this class are extremely hot and blue in color, with surface temperatures exceeding 30,000 K.
What nearby star is in the same spectral class as the sun?

Two stars of the same spectral class must have the same what?
Two stars of the same spectral class must have the same temperature and color. This classification system groups stars based on their temperature, with each spectral class representing a specific range of temperatures.
Is an O star blue or red?
A star with a spectral class of O is classified as a Blue Star. A red star will have a spectral class of M See related question
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.
