Meanings
- astronomyThe companion protostar in orbit around Betelgeuse.
The name Betelgeuse means “Hand of the Giant,” with “Elgeuse” being a historical Arabic name of the Orion constellation and a feminine name in old Arabian legend. Given that α Ori B orbits the hand of the giant, we suggest that the companion star be named سوارها (Siwarha), or “Her Bracelet.”

Origin
- Arabicسِوَارهَا
- EnglishSiwarha
Borrowed from Arabic سِوَارهَا (siwārhā, literally “her bracelet”), so named because Betelgeuse derives from Arabic يَد الجَوْزَاء (yad al-jawzāʔ, literally “hand of Jawzāʾ”); جَوْزَاء f (jawzāʔ, “Jawzāʾ”) is a female figure in Arabian legend.
