The Ancient Observatory, Dr. Wang Yumin said, the so-called "super moon" is the moon from earth near distance, the moon within a year to 12 times around the earth, and every month after the perigee, the nearest time may reach 350 thousand kilometers, generally in the 360 thousand to 370 thousand kilometers, so it is a relatively common phenomenon. And when the full moon is close to the time of the perigee, the "super moon" will be extraordinarily large. "The moon is more than two hours away from the perigee and the full moon, and it is indeed the closest to full moon since 1948."
