Milkomeda is a hypothetical galaxy formed by the merger of the Milky Way and Andromeda galaxies. This event is expected to occur in about 4.5 billion years, resulting in a new galaxy that may have a different structure and appearance. The name "Milkomeda" combines parts of both galaxy names, reflecting their eventual union. As these two massive galaxies collide, they will likely trigger new star formation and alter the orbits of existing stars and planetary systems, including our own Solar System.
