No, Earth does not belong to the Andromeda Galaxy. Earth is part of the Milky Way Galaxy, which is a separate galaxy from Andromeda. The Milky Way and Andromeda are two large spiral galaxies that are part of the Local Group, a collection of several dozen galaxies that are gravitationally bound to each other. While the Milky Way and Andromeda are the two largest members of the Local Group, they are distinct entities with their own sets of stars, planets, and other celestial objects. The Earth resides within the Milky Way Galaxy, specifically in one of its spiral arms called the Orion Arm or Local Spur.
