HD 180450 is a single [4] star in the northern constellation of Lyra, positioned about half a degree to the NNW of the globular cluster M56. [5] At an apparent visual magnitude of 5.88, [2] it is dimly visible to the naked eye under good viewing conditions. This star is located at a distance of approximately 1,400 light years from the Sun based on parallax measurements, but is drifting closer with a radial velocity of −64.4 km/s. [1]
This is an aging red giant star with a stellar classification of M1IIIab, [2] It is currently on the asymptotic giant branch, [6] having exhausted the supply of hydrogen in its core and evolved of the main sequence. It has expanded to ~68 times the radius of the Sun and is radiating a thousand times the Sun' luminosity from its enlarged photosphere at en effective temperature of 3,947 K. [1]
BE Camelopardalis is a solitary variable star in the northern circumpolar constellation of Camelopardalis.
