Antlia (Pronounciation:Ant-le-ah, Abbrev:Ant, Latin:Antliae) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Antlia takes up 238.901 sq. degrees of the night sky which equates to 0.58% of the night sky. The constellation gets its name as it name means Air Pump . It was not one of the original constellations that had been devised by Ptolemy, instead it was created by AbbÃ© Nicolas Louis de Lacaille years later.
Antlia is not a member of the Zodiac group of twelve constellations that appear when the Sun sets. Antlia is a southern hemispheric constellation which means it can't be seen easily or at all from the northern hemisphere.
The brightest star in Antlia is Alpha Antliae. There are 4 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site. There is a dedicated page for exoplanets in Antlia. For a list of named stars, that is stars that don't start HD or HIP, please visit Antlia Star List Page.
The number of stars that have been catalogued as part of the Hipparcos Star Catalogue from Antlia is 688. The number of stars that are of magnitude 6.0 or lower in the constellation is 22. The number of stars in the constellation that make up the outline is 4.
There are no deep space objects that were identified by Charles Messier in this constellation. There are no non-Messier deep space objects in this constellation that are covered at present on this site.
The nearest star to Earth is HIP 48659 which is roughly about 36.93 Light Years from the Earth. The nearest star to the Earth with an exoplanet is HD 93083 which is about 90.85 Light Years. The furthest star that can be located in the constellation is HIP 47907 which is located about 163081.7 Light Years away from the Sun. The furthest figure is derived from either the 1997 or 2007 Hipparcos star catalogue parallax figure and it has been known to produce distances that are wrong.
The dimmest star that can be seen in Antlia with the naked eye is HD 83441. The dim star has an apparent magnitude of 5.96. The dimmest star that a person is able to see with their naked eye is 6.0 magnitude based on the table in the reference. Ref: University of Michigan
The caveat of these stars are that they are catalogued on this site. If you know of a star that is nearer or further then do let me know in the comments and I'll add it to the site. The stars mentioned are from the Hipparcos catalogue or have been added because of their special status.
There is no Greek Legend behind this constellation. Antlia, the Air Pump is not an old constellation that was created by Ptolmey but one created by Abbe Nicolas Louis de Lacaille.
There are 4 Meteor Showers that occur during the year within this constellation based on information gathered from Adam Mickiewicz University (Poland). The ones listed as the ones I've been able to find a date range for. For others if you have the time, you can visit the AMU site, obtains the SL value then use IMO tables to calculate the date. A lot of the Meteor Showers are weak and you need to do a lot of stargazing to spot them.

The Alpha Centaurids is a southern hemispheric meteor Shower that is situated within the boundaries of constellation of Centaurus. The Constellation is most famous for having the closest star to our own Solar System, the star in question being Rigil Kentaurus better known to some people as Alpha Centauri. The Alpha-Centaurids are close to the Beta-Centaurids, whilst the location is similar, the difference is mainly in hourly rate and their magnitude. The betas are more prolific and brighter of the two. Both inhibit the same rough location in the sky and about the same time of the year. The location are estimated where given information what I`ve seen is where they will radiate from. The radiate points are Rigil Kentaurus for Alpha and Hadar for Beta Centaurids.
Hadar is the lower of the two stars within the yellow circle on the image below. The upper star is Rigil Kentaurus, Alpha Centauri. Alpha Centaurids will appear closer to Rigil and Beta Hadar.
