天球赤道座標： 05^h 01^m 57.42611^s，−06° 56′ 46.3718″

格利泽3323 (GJ 3323, 也稱為LHS 1723) 位於波江座的一顆單星^[8]。它肉眼不可見，視星等為12.20^[2]。視差測量給出的距離估計為距太陽17.5光年^[1]。它正以 +42.3公里/秒的徑向速度漂移得更遠^[2]。大約104,000年前，這顆恆星被認為位於距太陽系7.34光年的範圍內^[9]。

格利泽3323的恆星分類為M4.0Ve^[3]。這顆恆星的質量是太陽的17%，半徑是太陽的19%，光度只有太陽的0.4%^[5]。

行星系統[编辑]

2017年3月15日，高精度徑向速度行星搜索器探測到兩顆圍繞格利泽3323運行的行星，儘管發現團隊認為格利泽3323 c是候選行星^[8]。內行星格利泽3323 b可能在其恆星的星周宜居帶內運行^[10]。
