Ara (Pronounciation:Are-ah, Abbrev:Ara, Latin:Arae) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Ara takes up 237.057 sq. degrees of the night sky which equates to 0.57% of the night sky. The constellation gets its name as it name means The Altar . The constellation is one of the original constellations that was devised by the Ancient Greco-Egyptian astronomer Ptolemy who lived between 90 A.D. and 168 A.D.

The nearest star to Earth is HIP 82724 which is roughly about 12.06 Light Years from the Earth. The nearest star to the Earth with an exoplanet is HIP 85523 which is about 14.81 Light Years. The furthest star that can be located in the constellation is HIP 86894 which is located about 108721.1 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 Ara with the naked eye is V862 Arae. The dim star has an apparent magnitude of 5.99. 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.
Ara represents the Centaur Chiron, usually described as upside down. For more on Chiron, have a look at Centaur .There are no major meteor showers that radiate from within this constellation.

As there's so many stars in the cosmos, not all the stars are listed here. The site has lots of stars not listed so if your star isn't listed and you know the Henry Draper or Hipparcos ID, type https://www.universeguide.com/star/ then followed by the HIPNNNNNN or HDNNNN where NNNNN is the number part of the name. The stars that I do list have either a traditional name, a bayer or other classification name.
