Venus and Jupiter accompany the omen of the moon.

In ancient times, people thought that Jupiter, Venus and the moon appeared in the sky together, which was a bad sign, that is, there might be drought, people would starve and there would be war.

The appearance of "Double Star Accompanying the Moon" is because Venus, the closest planet to the Earth, 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 astronomical phenomenon, which is both a "double star with the moon" and a "three-star line". Jupiter, Venus and the crescent moon are close at hand, which is a visual phenomenon. In fact, they are far apart, many times farther than the distance between the earth and the moon. Since the earth, the moon, Venus and Jupiter are roughly in a straight line, people can witness this spectacle. Among Jupiter, Venus and the moon, Jupiter is the largest, but the luminosity is the darkest. The moon is the smallest but brightest, mainly because Jupiter is far from the earth.
