Mu¹ Scorpii (μ¹ Sco / μ¹ Scorpii) is a star in the constellation Scorpius.
μ¹ Scorpii is an eclipsing binary of the Beta Lyrae type. Both components are blue-white B-type stars. The primary is a subgiant, while the companion is a cooler 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.
