A star is really meant to be a single stellar object, not just something that looks like a star from earth. However, in many cases, other objects, such as multi-star systems, were originally thought to be stars. Because people have historically believed these to be stars, they are type as such, but they are also typed as what we now know them to be. [ - ]

Stellar classification is a classification of stars based on their spectral characteristics. Most stars are currently classified using the letters O, B, A, F, G, K and M, where O stars are the hottest and the letter sequence indicates successively cooler stars up to the coolest M class. According to an informal tradition, O stars are "blue", B "blue-white", A stars "white", F stars "yellow-white", G stars "yellow", K stars "orange", and M stars "red." The spectrum letter designation is further enhanced by a numerical addition of 0-9 for tenths of the range between two star classes.,
