Mu Serpens
What is Mu Serpens
Mu Serpentis belongs to the head of the Serpent, the figure split in two halves that the Serpent Bearer holds across the summer sky. A white type A star roughly 170 light-years away, its crisp, cool-hued light is the signature of an atmosphere hotter than the Sun's. Modest to the unaided eye, its position nonetheless serves as one of the markers tracing the serpent's brow, just west of the splendid Northern Crown.
Where it is and when to see it
Mu Serpens lies in the southern celestial hemisphere. It is visible to the naked eye under a dark sky.
