Beta Scorpii (Graffias)
Sketch by Michael Vlasov
This pair of hot B-class stars lies about 530 light years away. Their separation of 14 arc seconds places them at least 2200 astronomical units from each other. Beta-1 has another companion hugging it much closer at .5 arc seconds. Both Beta-1 and Beta-2 are also thought to be spectroscopic binaries, bringing the total number of stars in the system to 5.

Michael,
Beautiful treatment of this visible pair as part of a multiple system target.
