not only an optical but also a physical binary star. Two almost equally bright components of 4.4mag and 4.5mag are separated by 27.1", so we can distinguish them in a good binocular. Both are still double, which we only notice in binoculars. At a distance of 9.3' to the southeast, we can additionally observe a third component of 5.1mag brightness, which is actually also a close binary. |
