No, the Andromeda Galaxy is not in our solar system. The Andromeda Galaxy is a separate galaxy that is part of the Local Group, which includes our Milky Way galaxy along with about 54 other galaxies.
To put it in perspective, our solar system is located within the Milky Way galaxy, which is a vast collection of stars, planets, and other celestial bodies held together by gravity. The Andromeda Galaxy is approximately 2.537 million light-years away from us and is the nearest spiral galaxy to the Milky Way.
While the Andromeda Galaxy is on a collision course with the Milky Way, with a predicted merger occurring in about 4.5 billion years, our solar system itself is situated firmly within the Milky Way. Thus, they are distinct entities in the universe, and the Andromeda Galaxy does not belong to our solar system.
