not only an optical, but also a physical binary star. Two almost equally bright components with magnitudes of 4.4 and 4.5 are separated by 27.1", so we can distinguish them well in a good binocular. Both are further doubled, which we can only perceive in a telescope. Additionally, at a distance of 9.3' to the southeast, we can observe a third component with a magnitude of 5.1, which is actually also a close binary star. |
