The open cluster IC 2602 (or Caldwell 102), in the constellation Carina, is also called Theta Carinae Cluster, because of the high brightness of this star.

When Lacaille discovered it in 1751, he immediately compared it to the Pleiades of the constellation Taurus, hence its name of Southern Pleiades (Pleiades) which remained.

At a distance of about 479 light-years from the Earth, the Southern Pleiades (other name) have an apparent magnitude of 1.9 and extend, dispersively, over 50 arc minutes.

At the bottom right of the image, there is a smaller open cluster, with a much weaker signal. In 1915, Philibert Jacques Melotte inscribed it in his Catalog at number 101.
