The constellation Antlia (Latin for pump) is a relatively new constellation as it was only created in the 18th century, being too faint to be acknowledged by the ancient Greeks. The IAU adopted it as one of the 88 modern constellations. Beginning at the north, Antlia is surrounded by the sea snake Hydra, the compass Pyxis, the sails (Vela) of the mythological ship Argo and finally the centaur Centaurus.

Notable deep sky objects
HistoryThe French astronomer Abbé Nicolas Louis de Lacaille created 13 constellations for the southern sky to fill some star poor regions, among them Antlia. It was originally denominated Antlia pneumatica (Latin for the air pump invented by Robert Boyle) which is why in English this constellation is also often called Air Pump. It is interesting to note that no attempt seems to have been made to assign Bayer letters according to their apparent brightness, and that beta and gamma are skipped. There is no mythology attached to Antlia as Lacaille discontinued the tradition of giving names from mythology to constellations and instead chose mostly names of instruments used in science. Notable and named stars
The faint star DENIS 1048-39, discovered in 2000 and located in the Antilia constellation, may be as close as 13.2 light years from the Sun.[link]
