Omikron Cassiopeiae (ο Cassiopeiae , förkortat Omikron Cas, ο Cas) som är stjärnans Bayerbeteckning, är en trippelstjärna belägen i södra delen av stjärnbilden Cassiopeja. Den har en skenbar magnitud på 4,50 och är synlig för blotta ögat. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 4,64 mas, beräknas den befinna sig på ett avstånd av ca 700 ljusår (220 parsek) från solen.

Omicron Cassiopeiae (ο Cas, ο Cassiopeiae) is a triple star system in the constellation Cassiopeia. It is approximately 700 light-years from Earth, based on its parallax. It is visible to the naked eye with a slightly variable apparent magnitude of about 4.5. The primary component, ο Cassiopeiae A, is a spectroscopic binary, and its close companion completes one orbit every 2.83 years (1,031.55 days). The system has also been resolved with interferometry.

Omicron Cassiopeiae (ο Cas, ο Cassiopeiae) is a triple star system in the constellation Cassiopeia. It is approximately 700 light-years from Earth, based on its parallax. It is visible to the naked eye with a slightly variable apparent magnitude of about 4.5. The primary component, ο Cassiopeiae A, is a spectroscopic binary, and its close companion completes one orbit every 2.83 years (1,031.55 days). The system has also been resolved with interferometry. The primary of this spectroscopic binary is a blue-white B-type giant star. It is classified as a Gamma Cassiopeiae variable and its brightness varies from magnitude 4.30 to 4.62. It is rotating at a speed of 375 km/s at its equator (close to its theoretical break-up velocity of 390 km/s), although because the pole is inclined 36 degrees, its projected rotational velocity is only 220 km/s. The nature of the secondary is not well known. Despite the fact that the secondary is 2.9 magnitudes dimmer than the primary, the secondary appears to have a mass similar to, or even larger than primary. It is possible that the secondary is a pair of early A-type main-sequence stars. A more distant companion, ο Cassiopeiae B, lies 33.6 arcseconds away. It is an eleventh-magnitude, F-type main-sequence star. Because it has a similar proper motion to the central system, it is assumed to be gravitationally bound.
