[Global Network Technology Reporter Lin Di] Astronomical experts previously said that the " super moon " will stage a rare "three consecutive bursts" in 2019, on January 21, February 19 and March 21. Among these three times, the second viewing effect is the best, that is, the fifteenth day of the first lunar month this year, the night of the Lantern Festival. By then, as long as the weather is fine, the Chinese public can enjoy a special "Super Lantern Festival".
It is understood that the "super moon" is a common astronomical phenomenon, and its accurate name in astronomy is "period synodic moon ". Specifically, during a new moon, or full moon, the moon is closer to the Earth than usual, so it appears larger and rounder.
Astronomy experts explained that the moon’s orbit around the earth is non-standard elliptical, so the distance between the moon and the earth is not constant. The average distance between the moon and the earth is about 384,000 kilometers, the nearest is about 360,000 kilometers, and the farthest is about 400,000 kilometers. This change in the distance between the moon and the earth leads to changes in the apparent diameter of the moon. "Super Moon" When the moon moves to perigee and happens to be full, in theory, it is about 14% larger and about 30% brighter than the full moon we see at apogee.
Astronomy education expert and director of the Tianjin Astronomical Society Zhao Zhiheng said, "As the 'biggest and fullest moon of the year,' the fullest moment of the Lantern Festival in 2019 occurs at 23:54 on the 15th day of the first lunar month. At this time, it is close to midnight. The Lantern Festival month also just rose to the highest position in the south, showing the beautiful scenery of ' bright moon in the sky' described in the poem.
