Why is "Super Annular Eclipse" the most anticipated astronomical phenomenon in 2020?

This year's solar eclipse seems to be customized for China, not only in China, but also on Sunday, Father's Day, and the largest annular eclipse in the history of 2 1 century. Super annular eclipse? It appeared on June 2 1 this year, and people paid great attention to it. The food fraction of this annular eclipse reached 99.7% (the ratio of coverage area to apparent diameter), which can be said to be the largest annular eclipse since 2 1 century. Gold ring? Also (named after the shape of the annular eclipse) is particularly thin.

Because the distance to the moon is close to the earth, China is not an area where annular eclipses often occur. Therefore, it can be said that the once-in-a-century annular eclipse with a food intake of 99.7% is very rare. This time, we can feast our eyes. Because the last annular solar eclipse on 20 19 didn't face China, most areas can only see partial solar eclipse at most, and some areas may not see partial solar eclipse for several days. However, this annular eclipse in 2020 can be seen all over the country. In the process of annular eclipse, the whole moon will cover the sun and automatically turn to the front of the sun, leaving only one circle around, so when the whole moon turns to the center, everyone sees only one circle outside the sun. This is what we call the Phnom Penh solar eclipse, also known as? Gold ring? Don't miss it when passing by, it may take ten years to miss this time.

But astronomical wonders seem to be seen at different times, fields and places, and must be seen at the right time and place. If we have enough time, place and people, we can see the annular eclipse more directly and clearly, so this annular eclipse is really a good opportunity for astronomy lovers. For us who only appear in China, because no one can guarantee this kind of thing.
