Terebellum is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is Latin. It is the name of HIP 98066 (ω Sgr, HR 7597) in constellation Sgr.
Etymology and History
Ptolemy's Almagest lists four stars in a quadrilateral with ω Sgr the first in the list (the others being a, b, c Sgr). Bayer (1603) concludes this list with the note after "c": Has quatuor multi Terebellum seu τετράπλευρον vocant. "Terebellum" means quadrilateral, so the name originally designated the asterism at the tip of the tail and not a specific star.
