The shape of the moon is from September 10 to 10/0, an auspicious day, the date and weather of the lunar calendar.

It is sunny and cloudy. September 10 is the fourth day of the eighth lunar month. The moon looks like a crescent moon. It appears in the western sky after sunset, and its height is low. At that time, the crescent moon is like a silver hook, and the shining Venus will perform "Autumn Language" at low altitude in the west. As long as the western horizon is not too high, you can enjoy the beauty of Venus approaching the waning moon.

Astronomically, the trajectory of the moon in the sky is called the white road, and the trajectory of the sun is called the ecliptic. White and the ecliptic are very close, and there is only an included angle of more than 5 degrees between them.

The five planets, including Venus, all run near the ecliptic, and the moon runs in the sky once a month along the ecliptic. In this way, in a month's time, the moon will pass through these planets in turn, forming a so-called planetary combination. It's just that every time the moon closes, the positional relationship and distance between the planet and the moon are different and look different. The closer the distance between them, the higher the rarity and the better the observation effect.
