10 Lacertae was one of the first O-type stars (along with
S Monocerotis) to be defined as an anchor point for the
MKK spectral classification; since the early twentieth century it has served as such a point. Specifically, the star is representative of O9V stars, meaning relatively cool O-type stars on the main-sequence.[8]
10 Lacertae has an 8th magnitude companion about one arc-minute away.[9]
