Mu-1 Scorpii is an [[eclipsing binary]] of the [[Beta Lyrae]] type. Both components are blue-white [[stellar classification|B-type]] stars. The primary is a [[subgiant]], while the companion is a cooler [[main sequence|dwarf]]. Due to occultation of the primary by the dimmer companion, the [[apparent magnitude]] of the system varies from +2.80 to +3.08 over the course of the binary's orbit, which takes 1.4402 days to complete. The system is approximately 822 [[light years]] from [[Earth]]. |

The Bayer designation Mu Scorpii (μ Sco, μ Scorpii) is shared by two star systems, in the constellation Scorpius:
- μ1 Scorpii - a binary star whose primary is named Xamidimura
- μ2 Scorpii (named Pipirima)
They are separated by 0.1° in the sky.
They are separated too into different asterism in Chinese astronomy. μ1 Scorpii was a member of asterism 尾 (Wěi), Tail and μ2 Scorpii was the sole star in asterism 神宮 (Shéngōng), Changing Room (of the temple). Both asterisms are part of the Tail mansion.[1]
