ACHERNAR

ACHERNAR - is the brightest star in the constellation Eridanus and the eighth brightest star in the nighttime sky. It lies at the southern tip of the constellation. The extreme rotation speed has flattened Achernar.
Achernar is a bright blue star of six to eight solar masses. It is a main sequence (dwarf) star, it is thousands of times brighter than the Sun. It is visible in the southern part of the night sky. It remains permanently below the horizon from many densely populated portions of Earth's northern hemisphere. From those Southern hemisphere countries from which it can be seen best, it is particularly conspicuous through being highest in the night sky in November when most other bright southern stars are skirting the horizon.

Until about March 2000, Achernar and Fomalhaut were the two first magnitude stars furthest in angular distance from any other first magnitude star in the celestial sphere. Antares, in the constellation of Scorpius, is now the most isolated first magnitude star.
Achernar spins so rapidly that its equatorial diameter is more than 50% greater than its polar diameter, and is approximately 144 light years from the Solar System.
