A wide double star, whose components have magnitudes of 4.4 and 5.5, are separated by 7 arc minutes, so they can be resolved with the naked eye. In a telescope, we can observe their distinct white and orange hues. It is an optical double star: the brighter component is located at a distance of 364 light-years, while the fainter one is 10 light-years closer. However, the brighter component is actually a very close physical double star, which can only be resolved with a large telescope. |
