NGC 2808 is a globular cluster^[6] in the constellation Carina. The cluster currently belongs to the Milky Way, although it was likely stolen from a dwarf galaxy that collided with the Milky Way. NGC 2808 is one of our home galaxy's most massive clusters, containing more than a million stars. It is estimated to be 12.5-billion years old.

The cluster is being disrupted by the galactic tide, trailing a long tidal tail.^[7]
