NGC 4567 and NGC 4568 are a pair of merging unbarred spiral galaxies situated approximately 124 million light years away (NED data) in the constellation of Virgo. The centers of the two galaxies are around 20,000 light years apart.
The merger should be complete in the next 400 million years when a single elliptical galaxy will be formed.
