Saturn's Moon Companion
Since there are no other bright celestial bodies around, this scene is very clear. Interested members of the public can also see Saturn's unique rings with the help of small telescopes. Saturn's period of revolution is 29.458 years, so every 15 years, Saturn's rings will "disappear".
Saturn is the farthest planet from the earth that can be seen by naked eyes. In the telescope, it looks like a straw hat with a wide and thin halo. Because Saturn just passed the sun some time ago, Saturn will appear in the eastern sky in the evening, reach the southern transit at midnight, and fall in the western sky before dawn. Saturn combined with the moon is not a very rare astronomical phenomenon.
