What does it mean for Mars to stay in Antares?

The so-called "Mars stays in Antares" is the combination of Mars and Antares. Mars is called "fluorescence" and antares is called "big Mars". When two "fires" meet, the sky is full of red light. The ancients called this astronomical phenomenon "Mars stays in Antares". The "encounter" between Mars and Antares is only a visual phenomenon. Mars is a close neighbor of the earth, with a distance of 1.52 1 astronomical unit. The sunlight it reflects takes only 12.6 minutes to reach the earth, while the light emitted by Antares takes 554 years to reach the earth. Therefore, their meeting is only close in the direction of sight, not really close. In ancient astrology, the heart is the symbol of the emperor, and flicker is an ominous sign. The ancients called the astronomical phenomenon that two "fires" met "Mars stays in Antares", which is a very unlucky astronomical phenomenon. But modern science has proved that this statement is groundless. The astronomical phenomenon of "Mars stays in Antares" occurred at 200 1 last time and at 20 16 next time.
