Antares is located in Cygnus, right?

Wrong. China's ancient constellations, such as antares, constellations and endurance, all belong to Scorpio in today's modern constellation system. Antares is obviously the second star of the "Heart" constellation, so it is also in Scorpio.

Antares (literally translated from English proper nouns: against Mars), the western name is Scorpio α, which means the brightest star in Scorpio and the fifteenth brightest star in the night sky. China was also called "fire" in ancient times, but later it was renamed "fire" to avoid being confused with Mars. In addition, there are aliases such as "Shangxing" (because in ancient times, its observer Kun Bo observed it near Shangqiu, Henan Province) and "Chen Da".

Tianjin, this star official belongs to Nudu near the Milky Way, and belongs to today's Cygnus. Tianjin, which means the ferry in the sky (also the source of today's Tianjin name, the typical star name is followed by a market name). Tianjin IV is one of the brightest stars, and its western name is α Cygnus, which means the brightest star in Cygnus and the 19 brightest star in the night sky. Tianjin IV is its western name, which means the tail of a swan.

So Antares does not belong to Cygnus, but to Scorpio.
