China News Service, Nanjing, August 2 (Reporter Yang Yanci) According to news from the Purple Mountain Observatory of the Chinese Academy of Sciences on the 2nd, Saturn, with its fascinating halo, launched an opposition on the same day.

At that time, the beautiful Saturn will open the viewing window, like the "Lord of the Rings" appearing in the sky at night.

  Saturn is the second largest planet in the solar system, second only to Jupiter in size, and a beautiful halo surrounds its equatorial plane.

Viewed from a telescope, Saturn looks like a "straw hat" and is also known as the "Lord of the Rings".

  According to astronomers, this unique "straw hat" is composed of broken ice pieces with a diameter of several centimeters to several meters. They revolve around Saturn at a rapid speed, showing a colorful light under the shining of the sun.

Therefore, Saturn has also become one of the most beautiful planets in the solar system.

  On weekdays, it is not easy to watch the "complete" Saturn. Only during the opposition period, when Saturn is closest to the earth and has the highest brightness, is the best time to observe.

According to calculations, the astronomical phenomenon of Saturn’s opposition to the sun occurs once every 378 days.

  When the sun opposes, Saturn and the sun are exactly on both sides of the earth, and the three are almost in a straight line.

At that time, Saturn will be visible all night, from the earth, you can see the side illuminated by the sun.

  Soon after sunset, Saturn will rise from the southeast sky and will be visible almost all night.

During the "sun opposition" period, as long as the sky is clear, interested members of the public can observe the beautiful halo of Saturn using small telescopes.

If the observation conditions are good, you can also see the "Cassini ring crack", which is the largest and most obvious crack in Saturn's halo.
