Galactic anticenterとは 意味・読み方・使い方

The galactic anticenter is a theoretical point in the sky that lies directly opposite the center of the Milky Way galaxy. Because this point is relative, it will vary depending on the location of the observer; it is not an actual fixed point in space. Most of the time, this term refers to the anticenter from the point of view of an observer on Earth. Moreover, it is to be noted that points within the sky are not confined to a finite area; in other words, two objects in different galaxies can both be in the galactic anticenter as long as they are in the direction opposite of the direction of galactic center (much like how the stars in a constellation may be completely unrelated despite appearing visually close to each other).
