Achernar is not visible from the Greek isles ( latitudes > 33?North ), hence the choice of Acamar as the river's end during the time of Hipparchus and later Ptolemy.

Achernar, however, was not visible to Ptolemy ( it is from Alexandria today due to precession ); its declination in 100CE was-67, making it invisible even at Aswan.

According to the quadrant, it is possible that the constellation Achernar "'( Alpha Eridani ) is bright star in this constellation that may have never been seen in Chinese skies.
24.
The WGSN approved the name " Achernar " for " Alpha Eridani A " on 30 June 2016 and it is now so entered in the IAU Catalog of Star Names.

LFASCU-2 departed Hawaii on 17 February 1945 on board the USS Achernar ( AKA-53 ) and LFASCU-3 left six days later onboard USS Cepheus ( AKA-18 ).

Located at the northern edge of the constellation and just southwest of Achernar is Alpha Hydri, a white sub-giant star of magnitude 2.9, situated 72 light-years from Earth.

These stars appear as 12 new southern constellations, but the globe of 1598 is the first surviving source that plots their locations reasonably accurately . ) Also notable is the inclusion of Achernar as Alpha Eridani.
28.
The most'remote'1st magnitude star from another 1st magnitude star is Fomalhaut which is nearest to Achernar ( 39 degrees ) and Antares which is nearest to Alpha Centauri ( also 39 degrees ).
29.
The effective temperature of Denebola's outer envelope is about 8, 500 projected rotational velocity of 128 km / s, which is of the same order of magnitude as for the very rapidly rotating star Achernar.

The group was first visited by an ANARE ( Australian National Antarctic Research Expeditions ) party in 1954; the island was renamed by ANCA after the star Achernar, which was used for an astrofix in the vicinity.
