What's the matter with the double star accompanying the moon appearing for two consecutive nights?

The binary moon, also called Jin Mu Moon, means that Venus, Jupiter and the moon appear in the night sky at the same time. The appearance of the binary companion moon is due to the planet closest to the earth, and Venus is catching up with Jupiter from west to east in its operation. First Venus caught up with the nearest Jupiter, and then the moon caught up with Jupiter. When the distance between them is the closest, it presents a special celestial phenomenon that is both a "double star with the moon" and a front line of Samsung.

The moon revolves around the earth once a month. In this process, the moon will pass through some bright planets in turn, forming the so-called' moon-earth planetary combination'. Although the phenomenon of "full moon" happens every month, the relative position of the planet and the moon will be different and the distance will be different every time. So it is rare for more than two planets to approach the moon at the same time.
