They both exert a strong gravitational pull on each other.
They are both moving away from each other.
They are both moving away from each other.
The Milky Way galaxy is larger than the Andromeda galaxy.
The Milky Way galaxy is larger than the Andromeda galaxy.
The Milky Way is a spiral galaxy, and the Andromeda galaxy is not.
The correct statement about these two galaxies is:
They both exert a strong gravitational pull on each other.
This gravitational attraction is leading to the eventual collision and merger of the Milky Way and Andromeda galaxies, which is predicted to happen in about 4 billion years. Contrary to the second statement, they are not moving away from each other but are instead moving towards each other. Regarding their size, the Andromeda galaxy is actually larger than the Milky Way. Both the Milky Way and the Andromeda galaxy are spiral galaxies, making the last statement incorrect.
