Terebellum (astronomy) : ウィキペディア英語版 | Terebellum (astronomy)
The Terebellum, by Ptolemy called τετράπλευρον (/tetrápleuron/), is a quadrilateral of stars in the constellation Sagittarius. It is formed of four 4th magnitude stars, all within two degrees of each other: * Omega Sagittarii, 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. The stars are not gravitationally bound to each other as they are at different distances from the Earth. ==External links==
* (Sagittarius ) in the LacusCurtius version of Star Names: Their Lore and Meaning.
