60 Sagittarii
star in the constellation Sagittarius
60 Sagittarii is a suspected binary star system in the southern constellation of Sagittarius. It has the Bayer designation A Sagittarii, while 60 Sagittarii is the Flamsteed designation. This naked-eye object forms the northwest corner of the asterism called the Terebellum and, with an apparent magnitude of approximately 4.84, it is the dimmest of the four stars in the Terebellum. It is located 379 light-years from the Sun, based on parallax, but is moving closer with a radial velocity of −51 km/s.
The visible component is an aging G-type giant star with a stellar classification of G6 III, having exhausted the supply of hydrogen at its core and expanded to 17 the Sun's radius. In the Bright Star Catalogue it was listed with a class of G6 III Ba0.2, suggesting it is a mild barium star and thus might have a white dwarf companion. It is a red clump giant, indicating it is on the horizontal branch and is generating energy through the fusion of helium at its core.

Why this record matters
A short description can identify a subject without explaining its stakes. For “60 Sagittarii”, the useful work is to connect “star in the constellation Sagittarius” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q1096786. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation.
