Astronomers predict that the largest super moon of 2022 will appear in the early morning of July 14. What exactly is a super moon? Let’s find out in this issue.

html On the night of June 14th, I believe many people saw a bright moon in the sky. I wonder if you have noticed that the moon on this day is larger than the previous full moon. This is actually a "super moon". However, some people were not able to observe the beautiful moon on this day due to weather reasons, so there is no need to feel too sorry, because in July, the largest super moon of 2022 will usher in, according to astronomers According to observations, the "super moon" we are looking forward to will appear in the early morning of July 14. This super moon will be larger than the one on June 14. Under good weather conditions, people all over the country You will be able to see this super moon.

Moon

The moon revolves around the earth in an elliptical orbit. According to scientific calculations, the moon's perigee distance is 363,104 kilometers, and its apogee distance is 405,609 kilometers. Normally, when the moon moves near the "perigee", At the same time, when the moon phase of the full moon is encountered, a "super moon" appears. The moon at this time will visually make people feel larger and brighter. A "super moon" that truly appears at perigee is rare in thousands of years.

Moon

Moon The revolution period is about 27.32 days. However, in the calendar, the moon's synodic periodic changes are used as a month. This cycle averages 29.53 days. The time difference between the two is mainly because the earth is also orbiting The sun rotates. Assuming that the moon starts to orbit between the earth and the sun, the moon takes 27.32 days to revolve around the earth. At the same time, the moon actually moves around the sun at an angle, so the moon still needs about 2 days. It takes time to move to the position of the first new moon , which results in the time between the two new moons being about 29.53 days. In the astronomical calendar calculation, 14 moon phase cycles and 15 perigee moon times Very close, that is to say, when the moon experiences 14 waxing and waning periods, a so-called "super moon" will appear. When the moon is at its fullest for the 14th time, it will be at or near the 15th periapsis moon at about the same time. Perigee.

The Earth and the Moon

In the astronomical calendar, 14 " synodic months " are 413.4 days, which is roughly equivalent to the 14 months of the lunar calendar. That is to say, every 413 days, we will see the true meaning of " "Super Moon" is a theoretical "super moon". In practice, the full moon before and after the calculated position will also appear at perigee. Some people also call this kind of full moon "super moon". moon".

We have calculated the date of the "super moon", but how many times have there been special super moons in the past 10 years?

Moon

According to statistics, there have been 11 "super moons" in the astronomical sense from 2011 to 2021, appearing on September 28, 2015, November 2016, December 3, 2017, and January 31, 2018. The five "super moons" on Sunday, May 26, 2021, etc. are the most special. The "super moon" that appeared on September 28, 2015 coincided with the Mid-Autumn Festival full moon; the "super moon" that appeared in November 2016 was the "closest" to the earth since 1948; December 3, 2017 The "Super Moon", the eighth full moon in the past 80 years, appeared; on January 31, 2018, the "Super Blue Blood Moon" appeared at the same time for the first time in the past 152 years. On May 26, 2021, the "Super Moon + Red Moon + Total Lunar Eclipse" group appeared.

Super Moon

So how many more "super moons" will there be in 2022?

According to astronomers' speculation, there will be two "super moons" in 2022. The first "super moon" is the full moon that occurs on the night of June 14. At 19:52, the first "super moon" in 2022 A perigee full moon appears. At this time, the moon appears larger and brighter than any time in the previous half year.The next "super moon" will occur in the early morning of July 14. According to astronomers' calculations, this "super moon" will be the largest full moon of the year. As long as the weather is clear, it can be observed in most areas of China. As of this "super moon", the moon is located near perigee. Although it is not a "super moon" in the full sense, in 2022, the moon will move closest to perigee, in the early morning of July 14 The moon you see will be big and bright enough.

Moon

According to astronomers’ speculation, around November 25, 2034, 12 years later, the largest “super moon” in the 21st century will be visible on the earth. This “super moon” appears because the moon is exactly in the Perigee is only 356,446 kilometers away from the Earth, which is the first time this century that the distance is less than 35,650 kilometers. The next one will occur on December 6, 2056. This time the distance between the earth and the moon is even closer than in 2034, only 356,425 kilometers.

July 14th is coming soon. If you haven’t observed the “super moon” carefully, then don’t miss the last “super moon” in 2022.
