Arae or GJ 666 A is a binary star system in the constellation Ara. The two stars share a highly elliptical orbit that takes several centuries to complete. The estimates of the period range from 693 to 2,200 years, and the average separation of the two stars is about 210 AUs. Although often called just 41 Arae, it is more accurate to call it 41 G. Arae, as the number 41 is the Gould designation.
