'''HD 181433'''是一颗距离地球大约87[[光年]]的[[恒星]]<ref name="vanleeuwen07" /><ref group="注">从视差可计算出距离（单位是秒差距）：<math>\textstyle =\frac{1000}{\mathrm{parallax\ in\ milliarcseconds}}</math>（parallax：视差，milliarcseconds：毫角秒）</ref>，位于[[孔雀座]]。根据[[SIMBAD]]的记载，它的[[恒星分类|分类]]为K3III-IV<ref name="simbad" />，这说明它处于[[红巨星]]和[[亚巨星]]的交界区。而这与它的光度性质是不符合的，因为它的光度只有太阳的0.308倍<ref name="bouchy">{{cite journal|title=The HARPS search for southern extra-solar planets.
