Omicron Persei (ο Persei, abbreviated Omicron Per, ο Per), also named Atik,[2] is a binary star in the constellation of Perseus.


ο Persei (Latinised to Omicron Persei) is the star's Bayer designation.

It bore the traditional name Atik (also Ati, Al Atik), Arabic for "the shoulder". Some sources, including a planetarium software package, an atlas,[3] and a web site[4] attribute the name Atik to the nearby, brighter star Zeta Persei. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN)[5] to catalogue and standardize proper names for stars. The WGSN approved the name Atik for Omicron Persei on 12 September 2016 and it is now so entered in the IAU Catalog of Star Names.[2]


USS Atik was a ship of the United States Navy.


Atik is a spectroscopic binary consisting of a spectral type B1 giant and a type B3 dwarf orbiting each other every 8.5 days.

In fiction[edit]

Omicron Persei is perhaps best known from the animated television series Futurama, where it is the Solar System of the Omicronians- a race of giant horned toad creatures. Its eighth planet is ruled by the despotic leader, Lrrr,[6] who loudly and frequently announces the name of his home system.

It has been featured in other science fiction including Star Trek, Mystery Science Theater 3000, and Transformers.
