敗臼增一 （南魚座β）在星表上是南天星座，南魚座內的一對聯星^[5]^[6]。它的視星等為肉眼可見的4.29等^[2]。依據從地球觀察得到的年周視差22.84mas^[1]，這顆恆星與太陽的距離是143光年。它的座標位置是X射線的發射源，亮度為7021884999999999999♠88.5×10²⁰ W，但這應該不是來自這顆A-型恆星^[11]，可能還有其它發射源。

Oblak（1978年）曾將其視為一顆三合星^[3]，但隨後就將其列為聯星^[5]^[6]。它的星等為4.29^[3]，主星A，是一顆白色的A型主序星，類型為 A1V^[4]。估計質量是2.3太陽質量^[8]，半徑是2.1太陽半徑^[9]。有效溫度是9,638K^[9]，來自光球層的發光強度是太陽亮度的37倍^[8]。紅外過量的證據顯示它有岩屑盤，估計其軌道距離主星12AU，溫度為188K^[9]。伴星B的星等為7.8，恆星分類為A2V，與主星距離30.3角秒^[5]^[6]。

敗臼增一相對於太陽以每秒14.4公里的速度在銀河系中移動。它投射的銀河軌道讓它在距離銀河中心23,900至28,300光年的軌道上運動^[12]。^{[來源可靠？]}

在中國，它與敗臼一（天鶴座γ）、敗臼二、敗臼三和敗臼四（英語：19 Piscis Austrini）組成星官敗臼^[13]^[14]。
