In the past two days, we can see the super moon photographed by many netizens abroad on the Internet, which is really like a science fiction blockbuster. When and where can we see the 2019 super moon? Can we watch it at home? Let's have a look!
What about the 2019 super moon
Zijinshan Observatory of the Chinese Academy of Sciences released a sky curtain notice on the 20th: in 2019, the 'super moon' will climb the sky curtain three times in a row, on January 21, February 19 and March 21 respectively. The public can enjoy the 'magic moon'.
According to experts from Zijinshan Observatory, in fact, the word 'super moon' is an emerging word, which has only been proposed for decades. It refers to the phenomenon that the moon is near perigee when the full moon occurs.
According to reports, because the moon's orbit around the earth is non-standard elliptical, the average distance between the earth and the moon is about 384000 km, the perigee distance is less than 360000 km, and the apogee distance is more than 400000 km. Therefore, the full moon at the near earth point looks about 14% larger and 30% brighter than the full moon at the far earth point. Therefore, the perigee full moon is also known as the 'super moon'.
Experts say that the 'super moon' is not mysterious. It always appears more or less several times a year.
In 2019, when three 'super moons' occur, the moon is very close to perigee. Among them, on January 21, the full moon occurs at 13:16 Chinese time, and the distance between earth and moon is about 357300 km; On February 19, the full moon occurred at 23:54, and the distance between earth and moon was about 356900 km; On March 21, the full moon occurs at 9:43, and the distance between earth and moon is about 360700 kilometers.
Among them, when it occurs on January 21, there will be a 'super total lunar eclipse' on the other side of the earth, but China is daytime at that time, and you may not see it. But don't regret that February 19 coincides with the Lantern Festival. The bright moon of the Lantern Festival will add atmosphere to the festival.
