(future galaxy resulting from merger of Milky Way and Andromeda)
Milkomeda (aka Milkdromeda) is a nickname given
to a future galaxy resulting from the
future Andromeda-Milky Way collision,
the galaxy merger of the Milky Way and
Andromeda (M31). This is expected to occur in about 4.5
gigayears, given their trajectories and masses.
