The following tables on this page gives the listing of the presently accepted constellations in the sky. All have been ratified and have been internationally agreed since 1930.

Table 1 gives the proper name of the constellation, followed by its genitive form, and the adopted three letters, and the mostly discontinued four letter abbreviation. I.e. The bright star in Aquila is Alpha (α) Aquilae, abbreviated as α Aql. This table also give the area in square degrees and the constellations order of size from Hydra (1) to Crux (2).

Table 2 is a more basic list of all the Modern Constellations, each being colour coded by dividing them into South, North, Equatorial and the Zodiac.

Table 3 gives a listing of the Top 10 smallest and largest constellations in the sky.

Table 4. gives some of the names of the traditionally known older constellation names that are either now unused or that have been abbreviated for practical use.

1) Argo Navis now includes Carina, Puppis and Vela. Pyxis was once named as Malus. Total Area for Argo Navis is 1867.267 square degrees or 4.53% of the entire sky.

2) Total spherical area of the entire sky is 41,252.9612494… square degrees or 12.5664 steradians.

3) Constellation areas are in some dispute, as the their totals do not add up exactly to the area of the entire sphere. Areas that are quoted in the literature are often given from English observer A. E. Levin during 1935. These were calculated by old seven digit logarithm tables, whose small cumulative errors are significant. The method used divides each part into sector, found by the differences in right ascensions and declinations within each constellations, then totals them up to get the constellation area. In 1937, another useful paper Constellations by D.F. Brocchi gives another set of results .
The boundary data is taken from Delporte boundaries, which are in epoch 1875.0

4) Scorpius is the name of the astronomical constellation, while Scorpio is the astrological name. Some older astronomical books before 1930, however, sometimes use Scorpio.

5) Southern Ophiuchus passes through the zodiac, making it the mostly unrecognised 13th zodiacal constellation. Some consider this part of the ecliptic as part of Scorpius, whose length on the ecliptic is only 6° 17′ while Ophiuchus is 18° 30′ or three times longer.

6) Nebeculae Major (NMa) culminates on 13th December.

7) Nebeculae Minor (NMi) culminates on 3rd October.

8) Three southern constellations and their genetive names are very confusing to the novice (and me!), and even the most skilful get them occasionally wrong. These are;
  a.) Corona Australis / Coronae Australis
  b.) Piscis Austrinus / Piscis Austrini
  c.) Triangulum Australe / Trianguli Australis

Mnemonically, I have remembered the words; Crown Bliss [same] for CrA; Two Venus & one Fishy for PsA, then trim-rally & tri-bliss for TrA. Another is the confusion with Pisces and Piscis Austrinus, being either two fishes or just one solitary fish. (Perhaps just remember the line, there are more fish in the zodiac than in Australia!)

9) Originally, Corona Australis was officially by the recognised as Corona Austrina. It has since been corrected, but still embarrassingly holds this other name in the original IAU legislation decree.

10) Simplest in constellation shape, having only four boundaries on the celestial sphere, totalling ten in number are; Canis Major, Corona Australis, Chamaeleon, Crux, Microscopium, Piscis Austrinus, Telescopium, Scutum, Sextans and Volans. Here Canis Major is the largest rectangular area, while Crux is the smallest. I.e. 380.1 sq. degrees to 68.4 sq.degrees, being 5.6 times bigger than Cruxs area) or 18% the size of Canis Major.

11) Variable stars designations sometimes use numbers to assigned them to their constellations. These are from 1 for Andromeda to 88 for Vulpecula (See Main Constellation List (Table 1, above), with the following numbers as; AS R0001, R0002 etc. This used designation also appears within the now continuously updated General Catalogue of Variable Stars (GCVS). Version 4.2.

Shortened Terms and Older Deleted Constellation Names

Reduction of some constellations names were mercifully made for some simplification. Many of the common ones appearing in the literature are listed in Table 3 below.

Those highlighted in RED are Southern Constellations, while those with an asterisks (*) are the now the universally accepted Shortened Constellation Names. Also Nebeculae Magellani are both the LMC & SMC

Useful Subconstellations for Amateurs

Table 5 lists the large constellations that have been reduced by roughly half their size to match more balanced areas. After the 1930 decision, several people had noted some flaws it the divisions of the constellations. I.e. D.F. Brocchi stated in 1937, the system of the constellations is not free from objectionable features, among which may be mentioned lack of compactness of form in some cases, the worst being Hydra, 108 degrees in length with an average width of 12 degrees.

Although not officially recognised nor stated (my invention here), it might be useful to further divide these much larger constellations, mostly so that sky maps are more equal in size. Also these two parts are best divided by their Latin terms, where Orientus is (East), Occidens is (West), Supernus (Superior) and Improbus (Inferior). (Australis and Borealis are already used in the constellations for north and south, so I have not adopted this here.)

Of course, there is nor superiority nor inferiority to their area, but they give an indication of their original northern origins — usually the northern parts of these constellations against the more modern southern additions. Best of all, this only enhanced nomenclature but does not destroy, challenge or recreate the now well-established eighty-eight constellations decided in 1930. It simply enhances the usefulness of areas of when spotting various deep-sky objects into less imposing star patterns.

Another advantage is to split large constellations from about −30° South declination, making firmer the division between the northern and southern skies. This is especially useful with large north-south oriented Eridanus, Virgo, Puppis and Cetus. Similarly, Hydra is split in two by right ascension, making observations of the two segments more logical instead of being spread over 7 hours RA or one-third of the entire sky circumference. Logically, dividing Hydra here is to detached it from the 11 hour RA in Epoch 1875.0, making more sensible pieces of near equal size, changing the area of Hydra of about 1,303 sq,deg, into about 713 for Hydra Occidens (East) and 590 sq.deg. for Hydra Orientus (West). These are more manageable areas, being similar to the constellations of Andromeda and Orion, respectively.

I have also calculated the respective areas for these subconstellations and now show the redistribution graphically. Here this becomes 88+32=120 constellations including subconstellations, or by divided Serpens, 89+32=121 constellations including these subconstellations.
