The four stars of the Terebellum	The Terebellum is positioned on the left side of Sagittarius in this 1825 drawing

The Terebellum, called τετράπλευρον (/tetrápleuron/) (meaning quadrilateral) by Ptolemy, is an asterism consisting of four 4th magnitude stars in the constellation Sagittarius:

Omega Sagittarii, also named Terebellum, at the northeast corner.
59 Sagittarii or b Sagittarii, at the southeast corner.
60 Sagittarii or A Sagittarii, at the northwest corner.
62 Sagittarii or c Sagittarii, at the southwest corner.^[1]

All four stars are within two degrees of each other. They are not gravitationally bound to each other and are at different distances from the Earth.
