Explanation
This question asks to determine which of the provided options is the closest galaxy to our own galaxy, the Milky Way. 1. The first option, the Andromeda Galaxy (M31), is indeed the closest spiral galaxy to the Milky Way and is on a collision course with our galaxy. It is approximately 2.537 million light-years away from us.2. The second option, the Sombrero Galaxy (M104), is an unbarred spiral galaxy in the constellation Virgo located 31.1 million light-years from Earth. 3. The third option, the Milky Way Galaxy, is our own galaxy, so it cannot be the closest to itself.4. The fourth option, the Pinwheel Galaxy (M101), is a face-on spiral galaxy distanced 21 million light-years away in the constellation Ursa Major.Based on the information above, the closest galaxy to ours is the Andromeda Galaxy.
