Gamma Piscis Austrini, Latinized daga γ Piscis Austrini ,shine tsarin taurari uku a kudancin tauraron Piscis Austrinus . Ana iya ganinsa da ido mara kyau tare da haɗuwa da girman gani na +4.448. Dangane da sauye-sauyen parallax na shekara-shekara na 15.1 mas kamar yadda aka gani daga Duniya, tsarin yana da kimanin shekaru haske 216 daga Rana.
Abubuwan A da B,tun daga shekara ta 2010, an raba su da 4 arc seconds a sararin sama tare da kusurwar matsayi na 255 °. Sashe na "A" kansa binary ne, wanda ya ƙunshi taurari biyu da ke kewaye da juna tare da Lokacin orbital na shekaru 15 da rabuwa da raka'a tara na astronomical,tare da haɗuwa da girman 4.59 . Sashe Aa yana da sau 2.65 fiye da Sun kuma sau 2.9 radius dinsa,kasancewa tauraron sunadarai na musamman tare da nau'in nau'in A0 Vp (SrCrEu). Ab bangare ne karami, a 0.94 sau yawan Sun da 0.84 sau radius. Abokin da yafi ƙanƙanta 8.20 aboki, bangare na B, babban tauraron jerin F ne tare da aji na F5 V. Yana da kashi 20% fiye da Sun kuma radius 15% ya fi girma.
Gamma Piscis Austrini yana motsawa ta cikin Galaxy a saurin 24.1 km / s dangi ga Sun. Tsarinsa na Galactic yana ɗauke dashi tsakanin shekaru-haske 6,624 parsecs (21,605 ly) da 30,903 daga tsakiyar Galaxy. Yazo mafi kusa da Sun 1.8 miliyan da suka gabata a nesa da 48.13 parsecs (157 ly).
Shekarar tsarin a halin yanzu shine shekaru miliyan 350. Zai zama tsarin fararen dwarf sau uku acikin shekaru biliyan 14.
