Achernar (also known as Alpha Eridani and Achenar, Romulan language: Atlai'fehill) was a B class star in the Romulan Star Empire, visible from Sol as the brightest part of the Eridanus constellation. (ST novel: Articles of the Federation)

The system's primary spins so rapidly that its equatorial diameter is more than 50% greater than its polar diameter. In the early 21st century, it was the least-spherical star known to Human astronomy. (Real-word information)

In 2156, the entity known as Redjac murdered several females in Heliopolis on Achernar II. (TOS episode: "Wolf in the Fold"; ENT novel: Beneath the Raptor's Wing)

The Achernar system could be visually seen from Space Station KR-3. In 2311, Elias Vaughn stood in front of a viewport on the space station and tested his memory, naming all the major stars he could see in Romulan space. (TLE novel: Serpents Among the Ruins)

In 2379, the system was captured by forces led by Commander Donatra, who proclaimed the system capital of a new Imperial Romulan State, of which she declared herself Empress. Donatra's government resided on the planet Achernar Prime. (ST novel: Articles of the Federation)

The starships USS Achernar and the Achernar-class of vessels were named for this star. (TOS reference: Star Fleet Technical Manual)
