Corona Australis (Pronounciation:Core-ona Ore-stra-liss, Abbrev:CrA, Latin:Coronae Australis) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Corona Australis takes up 127.696 sq. degrees of the night sky which equates to 0.31% of the night sky. The constellation gets its name as it name means The Southern Crown . 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.
Corona Australis is not a member of the Zodiac group of twelve constellations that appear when the Sun sets. Corona Australis is a southern hemispheric constellation which means it can't be seen easily or at all from the northern hemisphere.
The number of stars that have been catalogued as part of the Hipparcos Star Catalogue from Corona Australis is 485. The number of stars that are of magnitude 6.0 or lower in the constellation is 28. The number of stars in the constellation that make up the outline is 7.
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 89211 which is roughly about 42.74 Light Years from the Earth. The nearest star to the Earth with an exoplanet is HD 166724 which is about 138.03 Light Years. The furthest star that can be located in the constellation is HIP 94864 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 Corona Australis with the naked eye is HD 179433. The dim star has an apparent magnitude of 5.91. 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.
Believed to be the fallen crown of Sagittarius .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.
