On the morning of the 7th, Tianyu Group "grinned".

"Accompanying the moon" generally refers to the astronomical phenomenon that one or several bright stars (either planets or brighter stars) appear near the moon.

Zhao Zhi Heng, an expert in astronomical science and director of Tianjin Astronomical Society, said that at the beginning of 20021,Saturn and Jupiter were obscured by the sun's brilliance and could not be observed. It was not until April that they "got rid of" the light of the sun, and the observation conditions became better and better. Before sunrise, people can see them at low altitude in the southeast.

Saturn and Jupiter rendezvous with the moon on April 6 16 and April 7 15, respectively. Before sunrise on the 6th, 7th and 8th, the waning moon will move closer to Jupiter and Saturn, forming an astronomical landscape of "double stars accompanying the moon", and the angular distance between the three celestial bodies is relatively close. Among them, Jupiter is at the lower left and Saturn is at the upper right. Especially in the early morning of April 7, the waning moon hangs obliquely between Jupiter and Saturn, which looks like a "crooked smile".

"On the same day, the brightness of Jupiter was around -2, and the brightness of Saturn was around 0.75. Because Saturn is darker than Jupiter, one eye is bright and the other eye is slightly dark in this evil smile. " Zhao Zhi Heng said.

Saturn is one of the most beautiful planets in the night sky. In the telescope, it looks like a straw hat and is called the "Lord of the Rings". Jupiter is the largest planet in the solar system, known as the "giant planet" and the "old star" in ancient China.
