Our galaxy, the Milky Way, will also collide and merge with our neighbor, the Andromeda galaxy, which is currently 2.5 million ly from Earth.
About 4 billion years from now, the two will collide; 2 billion years later, the two galaxies will merge to form a single galaxy.
Earth will be toast long before the collision as our Sun will evolve into a red giant. 🍞 ☀️

  Andromeda Galaxy
  The Andromeda Galaxy is a barred spiral galaxy and is the nearest major galaxy to the Milky Way. It was originally named the Andromeda Nebula and is cataloged as Messier 31, M31, and NGC 224. Andromeda has a D25 isophotal diameter of about 46.56 kiloparsecs (152,000 light-years) and is approximately 765 kpc (2.5 million light-years) from Earth. The galaxy's name stems from the area of Earth's sky in which it appears, the constellation of Andromeda, which itself is named after the princess who was the wife of Perseus in Greek mythology. The virial mass of the Andromeda Galaxy is of the same order of magnitude as that of the Milky Way, at 1 trillion solar masses (2.0×1042 kilograms). The mass of either galaxy is difficult to estimate with any accuracy, but it was long thought that the Andromeda Galaxy was more massive than the Milky Way by a margin of some 25% to 50%.
