What is the constellation between Scorpio and Sagittarius?

It's always the constellation 12. Recently, astronomers found that the sky has changed, and the constellation 12 was the expression of the sky more than 2000 years ago. Because the constellation has changed, astronomers think that a snake man should be added between Scorpio and Sagittarius in 12 constellation, so that Scorpio becomes a six-day shooter, and subtracting some days will form a tangled Ophiuchus. There has always been, but constellation experts don't recognize the 13 constellation. Some people think that astronomy is different from astrology and includes more constellations. The theory that 12 constellation represents people's personality is debated endlessly, but in any case, the constellation can't completely believe that it can't represent everyone, so it is better to believe it for fun.
