The third largest full moon this year affects Saturn's rushing in the sun and Yingxian meteor shower?Can wait for a few days to watch with Moonlight "Peak"

Author:Report Time:2022.08.13

During the day, the summer is hot, and when the night comes, the deep starry sky is wonderful. I just sent away the third largest full moon that appeared in the Zhongyuan Festival. This morning, the Yingxian meteor shower was extremely heavy. In the early morning of the 15th, Saturn, which had the reputation of "Ring Ring", was about to rush.

It is a pity that Haoyue has been empty all night in the past few days, and it has interfered with the starlight. Fortunately, the "rewarding period" of these two heavenly phenomena is relatively long. Interested citizens may wish to stay for a few days to "peak the peak" with the moonlight to better appreciate the bright Saturn and "San Loron's tears".

In the solar system, Saturn is the second largest planet after Jupiter. This giant giant star not only has more than 80 satellites, but also wraps around a planet ring composed of ice particles, rock wreckage and dust. From the perspective of the earth, this beautiful planetary ring seems to be a large straw hat. With the rotation of Saturn, different aura of width is revealed every year.

The so -called Saturn rushing to the sun means that when the earth comes between Saturn and the sun, the three are generally called Saturn's Richy Rich. Before and after the day, Saturn is the closest to the earth, with the largest diameter and the highest brightness -if you observe it with a telescope, you will find that the Saturn at this time is shining like a full moon.

Shi Yan, Minister of the Department of Popularization of the Shanghai Observatory and Deputy Secretary -General of the Shanghai Astronomical Society, introduced that Saturn's rotation cycle is 29.5 years, and the convergence cycle with the Earth is 378 days. Therefore, Saturn's date is delayed by about 13 days than the previous year. This year, Saturn's rushing day occurred at 1:10 on August 15. On August 14, Saturn will rise from the east part of the east after the sun falls. It will pass the sky around the middle of the night, and it will fall in the south of the west during the sunrise. It can be seen all night.

He particularly reminded that because the moon tonight is not too far from Saturn, it may have a certain impact on observation. "In fact, two or three weeks around the day and after the day are the best time to observe the planet outside the earth. Citizens may wish to wait for another three or five more On the day, avoid the edge of the moonlight to see again. "

"Every 15 years, Saturn halo will face the earth from the maximum angle, and its beautiful" straw hat along "will be very clear; otherwise, the Saturn halo will be thin and difficult to see." Shi Yan said that by 2025, 3 In the month, Saturn halo will "disappear", so this year can still see a narrow Saturn halo.

However, the more romantic natural phenomenon in the past few days is the Yingxian meteor shower that has almost never been absent. The Yingxian meteor shower, known as "Saint Loron's Tears", is one of the three major meteor shower in the northern hemisphere, and is known for its bright fire meteor. In the early morning of this morning, when many astronomical fans were waiting for the meteor shower, they saw the green and bright firearms crossed through the sky.

According to astronomical forecast, this year's Yingxian meteor shower is extremely large with a large value of about 100 days per hour. Shi Yan introduced that in the past few days, the Yingxian seat will rise from the horizon of the northeast. Until the dawn, the radiation point is close to the sky, which is a great time for meteor shower. It is a pity that in the past few days, Haoyue is empty, and the bright moonlight will flood those slightly darkest meteors. Citizens can also avoid moonlight interference in a few days, and then appreciate "Saint Loron's tears".
