Andromeda A, also known as Sidious II, is a blue-and-white star with a magnitude of 2. 1, and its brightness will change slightly. Andromeda y, also known as general I in the sky, is a fascinating star gathering system. Through a small astronomical telescope, we can observe a yellow star with a magnitude of 2.3 and a blue star with a magnitude of 4.8. The blue star has a relatively dim half star with a magnitude of 6. 1. 20 12, from the earth, this blue star and its companion star are almost in a straight line. At present, they have gradually separated. When the two stars are in a straight line, even with the largest Tianmen telescope, it is impossible to distinguish two people.
