See the moon shine near the claws of the Scorpius constellation just after dusk Friday night (Sept. 2). 

The nearly half-illuminated moon rises tonight in the southwestern sky. It will appear near the row of small white stars that form the claws of Scorpius, which, from top to bottom, includes Jabbah or Nu Scorpii, Graffias or Acrab, Dschubba, Pi Scorpii, and Rho Scorpii.

While some of the stars are visible to the naked eye, others are best observed with binoculars or telescopes. Viewers using a backyard telescope at high magnification will be able to see that Nu Scorpii, Graffias, and Dschubba are close-together double stars, according to geophysicist Chris Vaughan, amateur astronomer with SkySafari Software who oversees Space.com's Night Sky calendar

Pi Scorpii, or Fang, and Rho Scorpii are also multi-star systems. Pi Scorpii consists of three stars, which have a combined magnitude of 2.9, while Rho Scorpii is a double star with a magnitude of 3.87, which is bright enough to be seen with the naked eye. 

Acrab, Dschubba and Fang are also commonly referred to as the Crown of the Scorpion because they form a curved arc that marks the scorpion's head. 

Viewers can use the moon as a guide to find Scorpius, as it rises closest to Dschubba, which is easy to spot as it shines with a magnitude of 2.32. At this brightness, it can be seen by the naked eye under clear, dark skies.
