Antlia (; from Ancient Greek ἀντλία ) is a constellation in the southern sky.

The constellation was created in the 18th century from an undesignated region of sky, so the stars comprising Antlia are faint.

Antlia is bordered by Hydra the sea snake, Pyxis the compass, Vela the sails, and Centaurus the centaur.

NGC 2997, a spiral galaxy, and the Antlia Dwarf Galaxy lie within Antlia's borders.

Johann Bode's depiction of Antlia.

Antlia was created in 1756 by the French astronomer Abbé Nicolas Louis de Lacaille, who created fourteen constellations for the southern sky to fill some faint regions.

Though Antlia was technically visible to ancient Greek astronomers, its stars were too faint to have been included in any constellations.

It was originally named Antlia pneumatica (" Machine Pneumatique " in French ) to commemorate the air pump invented by the French physicist Denis Papin.

Lacaille and Johann Bode each depicted Antlia differently, as either the single-cylinder vacuum pump used in Papin's initial experiments, or the more advanced double-cylinder version.

There is no mythology attached to Antlia as Lacaille discontinued the tradition of giving names from mythology to constellations and instead chose names mostly from scientific instruments.

Because it occupies a part of the celestial sphere that faces away from the Milky Way, Antlia contains very few deep-sky objects.

It is the brightest galaxy in Antlia at an integrated magnitude of 10. 6.

The Antlia Dwarf, a 14. 8 < sup > m </ sup > dwarf spheroidal galaxy that belongs to our Local Group of galaxies.

Chinese astronomers were able to view what is modern Antlia from their latitudes, and incorporated its stars into two different constellations.

Several stars in the southern part of Antlia were a portion of " Dong ' ou ", which represented an area in southern China.

* The membership of NGC 3109, and its companions Sextans A and the Antlia Dwarf, is uncertain due to their extreme distance from the center of the Local Group.

Ninety-eight percent can be found in the following 11 clouds ( given in decreasing order of number of luminous galaxies ): Canes Venatici, Virgo Cluster, Virgo II ( southern extension ), Leo II, Virgo III, Crater ( NGC 3672 ), Leo I, Leo Minor ( NGC 2841 ), Draco ( NGC 5907 ), Antlia ( NGC 2997 ) and NGC 5643.

NGC 3109 is believed to be tidally interacting with the dwarf elliptical galaxy, Antlia Dwarf.

The warp has the same radial velocity as gas in the Antlia Dwarf galaxy, indicating that the two galaxies had a close encounter approximately one billion years ago.

HD 93083 is an 8th magnitude star located approximately 94 light years away in the southern constellation of Antlia.

It was located between the constellations of Antlia and Hydra.
