Missed last month's Super Blood Wolf Month? It doesn't matter, tonight, "Supermoon" will accompany you to spend the Lantern Festival.
At 17:02:43 on February 19, the Moon and Earth will have the "closest contact" of the year, and the best moon viewing moment will be ushered in in the early morning hours, are you ready?
Data chart: On January 21, 2019, local time, many places in Europe and the United States staged the "Super Wolf Blood Moon".
[When you don't know the moon when you are young- what is a "supermoon"? 】
As the saying goes, "the fifteenth moon is sixteen round", but in 2017 and 2018, a full moon will rise in front of the window on time on the fifteenth lantern festival of the first lunar month every year, and this year is no exception.
What is even more surprising is that the one who appears in the night sky tonight will be the "supermoon".
What is a "supermoon"? The term was coined by the American astrologer Richard? Noel was founded in 1979 to describe the astronomical sight of the Moon passing through perigee during a new or full moon.

The Moon orbits the Earth and its orbit is not standard elliptical. When the Moon travels to perigee, it is closest to Earth, about 360,000 kilometers. According to the law of "near large and far small", the moon at this time looks the largest, which is the "supermoon".
Around the "supermoon", there are many mysterious stories circulating in many parts of the world. In fact, the "supermoon" does cause some changes, because when the distance between the moon and the earth becomes shorter, the tidal force of the moon will be greater.
Who can sit idly when they see the moon - "super moon" is really "super big"? 】
How much is a "supermoon" bigger than a normal moon? If you really want to reveal this mystery, the "melon eating audience" in the front row may be disappointed. Although its apparent diameter has increased by 14% and brightness by 30%, the "supermoon" is no different from the ordinary full moon observed by the human eye.
So, is a "super full moon" rare? Not really. The moon orbits the earth more than a dozen times a year, and people have the opportunity to see it every year. This year, "Supermoon" will appear in the sky three times, and in addition to the past January 21, it will also appear for the third time on March 21.
However, tonight's "super moon" and the Lantern Festival on the fifteenth day of the first lunar month will still be a good play not to be missed.
Prior to this, such a "Super Lantern Moon" appeared on February 26, 2002 and February 28, 2010, respectively, and the next time you want to invite "Super Moon" at the Lantern Festival, you will have to wait until February 9, 2028 and February 11, 2036.
More importantly, judging from an astronomical point of view, the "Super Lantern Moon" before and after this is slightly inferior to tonight.
