Distance measurement
In 1982 Wilhelm Gliese published photometric distance of LHS 1723 (0.161 mas), and in 1991 it was included to the 3rd preliminary version of catalogue of nearby stars by Gliese and Jahreiss as NN 3323 (also designated as GJ 3323) with photometric parallax 6993790246300208545♠163.0±26.0 mas.
Its trigonometric parallax remained unknown until 2006, when it was published by RECONS team. The parallax was 6993911061869541042♠187.92±1.26 mas.
