HD 172044 and BD+33°3154B are two components of a binary star system in the constellation Lyra, approximately 520 light years away from Earth. 5th magnitude HD 172044 is a giant or subgiant star with the spectral type B8II-IIIp... The "p..." signifies that the star has a peculiar spectrum and spectral peculiarities have yet to be described. It is bluish white in color and has a surface temperature of 11,000 to 25,000 kelvins. It is therefore at least twice as hot as our Sun on its surface, and many times brighter and larger in size. BD+33°3154B is an 11th magnitude star of an unknown spectral type.
