Iota Gruis, Latinized from ι Gruis, is a binary star system in the southern constellation of Grus. It has an apparent visual magnitude of 3.90, which is bright enough to be seen with the naked eye at night. The distance to this system, as determined using an annual parallax shift of 17.80 mas as seen from the Earth, is about 183 light years.

  • Iota Gruis, Latinized from ι Gruis, is a binary star system in the southern constellation of Grus. It has an apparent visual magnitude of 3.90, which is bright enough to be seen with the naked eye at night. The distance to this system, as determined using an annual parallax shift of 17.80 mas as seen from the Earth, is about 183 light years. This is a single-lined spectroscopic binary with an orbital period of 409.6 days (1.121 years) and an eccentricity of 0.66. The yellow-hued primary component is an evolved K-type giant star with a stellar classification of K1 III. It is an X-ray emitter with a flux of 441.31×10−17 W/m2. (en)

  • Jota Gruis (ι Gruis, förkortat Jota Gru, ι Gru) som är stjärnans Bayerbeteckning, är en dubbelstjärna belägen i den östra delen av stjärnbilden Tranan. Den har en skenbar magnitud på 3,90 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 17,8 mas, beräknas den befinna sig på ett avstånd på ca 183 ljusår (ca 56 parsek) från solen. (sv)
