Its main star, Mu Herculis A is fairly similar to the Sun although more highly evolved with a stellar classification of G5 IV. Since 1943, the spectrum of this star has served as one of the stable anchor points by which other stars are classified.〔 Its mass is about 1.1 times that of the Sun, and it is beginning to expand to become a giant. The secondary component consists of a pair of stars that orbit about each other with a period of 43.2 years.〔 Mu Herculis A and the binary pair B-C are separated by 286 AUs. The stars B-C are separated from each other by 11.4 AUs. Their orbit is quite elliptic (e=0.18) and both stars swing each other between 9.4 and 13.5 AUs. == Etymology == In the catalogue of stars in the ''Calendarium of Al Achsasi Al Mouakket'', this star was designated Marfak Al Jathih Al Aisr, which was translated into Latin as Cubitum Sinistrum Ingeniculi, meaning ''the left elbow of kneeling man''.〔 In Chinese, (), the ''Left Wall of Heavenly Market Enclosure'', refers to an asterism which represents eleven old states in China, marking the left borderline of the enclosure, consisting of μ Herculis, δ Herculis, λ Herculis, ο Herculis, 112 Herculis, ζ Aquilae, θ1 Serpentis, η Serpentis, ν Ophiuchi, ξ Serpentis and η Ophiuchi.〔 ''中國星座神話'', written by 陳久金. Published by 台灣書房出版有限公司, 2005, ISBN 978-986-7332-25-7.〕 Consequently, μ Herculis itself is known as (, (英語:the Third Star of Left Wall of Heavenly Market Enclosure)), represent ''Jiuhe'' (九河, lit. meaning ''nine rivers''), possibly for Jiujiang, the prefecture-level city in Jiangxi, China, which is the same literally meaning with ''Jiuhe''.〔 (AEEA (Activities of Exhibition and Education in Astronomy) 天文教育資訊網 2006 年 6 月 23 日 )〕〔 (English-Chinese Glossary of Chinese Star Regions, Asterisms and Star Name ), Hong Kong Space Museum.
