Depiction of the Auriga constellation.

The Galactic anticenter is a direction in space that is directly opposite the direction toward the Galactic center as seen by an observer on Earth. This direction corresponds to a point on the celestial sphere. From the perspective of an observer on Earth, the Galactic anticenter appears within the constellation Auriga, and Alnath is the closest bright star to this point.

In terms of the Galactic coordinate system, the Galactic center in Sagittarius corresponds to a longitude of 0°, while the anticenter is located exactly at 180°.[1] In the equatorial coordinate system, the anticenter is found at roughly R.A. 05h 46m, Dec. +28° 56'.[2]
