The Milky Way galaxy, which we belong to, and our closest neighbor galaxy, the Andromeda are destined to come together.
Not to worry though. This collision should not occur or 4 billion years! And, another reason not to worry, the Earth and solar system are in no danger of being destroyed.
The two galaxies are currently 2.5 million light-years away from each other. The mutual pull of gravity between the two galaxies is making the Andromeda galaxy fall toward the Milky Way galaxy.
