It isn't. Unless they're interested in knowing something about the world beyond our Earth.
Madalynne Braseltonstellar classification is the classification of stars based on their spectral characteristics
no beacuse its a little to stellar.

It is a star that has entered the super-giant phase. Its stellar classification is K2 1b.
== == No our Sun is a G2V star. See related link for more information on stellar classification
Yes.
Classification is so useful since it makes it easy for things to be identified. Things and organisms are normally classified depending on their features and characteristics. This is not right, i think
Yes it can
Alpha Ophiuchi is considered to have a stellar classification of A5 III, which makes it a "normal" giant, not a supergiant.
The red giant galaxies are large non-main sequence star of stellar classification. These are classified K or M because of the reddish appearance of the cooler giant stars.
Many people were involved in the current spectral classes.The person who first realised that the spectral sequence then categorised was in fact temperature, was Cecilia Payne.See related link for more information on her.
Henry Norris Russell was an American astronomer renowned for his contributions to the field of astrophysics, particularly in the study of stellar classification and the Hertzsprung-Russell diagram, which illustrates the relationship between a star's luminosity and its temperature. He played a significant role in advancing our understanding of stellar evolution and the structure of the Milky Way galaxy. Russell's work laid the foundation for modern stellar classification systems and helped in deciphering the life cycles of stars.
