The name of the star may be derived from Greek. syrein - plod around. The ancient Greeks called the word Sirma a dress with a long train, used in ancient tragedies. In the constellation Virgo, this star is part of a similar dress at the right foot of Virgo.
According to another version, the star’s name is based on the Arabic word سرما (تطريز sirmā , meaning "train of clothes". [5]
To avoid confusion, in 2016 the International Astronomical Union (IAU - International Astronomical Union) organized a working group Working Group on Star Names (WGSN) to organize star names. [6] [7] [8] On the Wikipedia pages, this function was partly taken over by the Nippy Astro Club [9] (Astro-Club "Nippy"), part of the IAU Handbook of International Astronomy and participating in 2015 in the IAU's NameExoWorlds [10] [11] campaign to name recently discovered stars and planets.
