Pi Ceti, Latinized from π Ceti, is the Bayer designation for a star system in the equatorial constellation of Cetus. It is visible to the naked eye with an apparent visual magnitude of 4.238. Observed to have an Earth half yearly parallax shift of 8.30 mas, it is around 393 light years from the Sun. The primary, component A, is a normal B-type star that has been given stellar classifications of B7 V and B7 IV. It appears very young – less than half a million years in age – and may still be on a pre-main sequence track. The star shows no magnetic field but it does emit an infrared excess.

  • Pi Ceti (π Cet / π Cet) adalah bintang dengan tipe B7, yang berada di rasi Cetus dan memiliki magnitudo 4.24. Pi Ceti adalah bintang yang berada pada jarak 441 tahun cahaya dari Bumi. (in)
  • Pi Ceti (π Ceti / π Cet) est une étoile binaire de la constellation équatoriale de la Baleine, située à la limite avec l'Éridan. Elle est visible à l'œil nu et sa magnitude apparente est de 4,24. Le système présente une parallaxe annuelle de 8,30 mas telle que mesurée par le satellite Hipparcos, ce qui permet d'en déduire qu'il est distant d'environ 120 pc (∼391 a.l.) de la Terre. Il s'éloigne du Système solaire à une vitesse radiale héliocentrique de +15 km/s. (fr)
  • Pi Ceti (π Cet / π Ceti) è una stella di magnitudine 4,24 situata nella costellazione della Balena. Dista 392 anni luce dal sistema solare. (it)
  • Pi Ceti (π Ceti, förkortat Pi Cet, π Cet) som är stjärnans Bayerbeteckning, är en dubbelstjärna belägen i den östra delen av stjärnbilden Valfisken (stjärnbild). Den har en kombinerad skenbar magnitud på 4,24 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 8,3 mas, beräknas den befinna sig på ett avstånd av ca 393 ljusår (ca 120 parsek) från solen. (sv)
