The annual parallax shift of 10.57 mas[1] indicates it is roughly 310 light years away.
The star shows acceleration components in its proper motion, indicating with high probability that it is an astrometric binary.
[9] The visible component is an evolved K-type giant star with a stellar classification of K5 III.
[10] The measured angular diameter is 3.71±0.10 mas,[11] which, at the estimated distance of Kappa Librae, yields a physical size of about 38 times the radius of the Sun.
[6] It radiates 296 times the solar luminosity from its outer atmosphere at an effective temperature of 3,930 K.[7] In Chinese astronomy, Kappa Librae is called 日, Pinyin: Rì, meaning Sun, because this star is marking itself and stand alone in Sun asterism, Room mansion (see : Chinese constellation).
