@CNN: This image of the first supermoon of 2018 was taken in Nara, Japan. The event occurs when the moon becomes full on the same day that it reaches its perigree, the point in the moon’s elliptical orbit when it is closest to Earth. https://t.co/BJtVSWBn3j Photo credit: Dennis Doucet https://t.co/gcLZyk4zhu
