According to the original definition of supermoon – coined by Richard Nolle in 1979 – a moon has to come within about 224,000 miles (361,000 km) of our planet, as measured from the centers of the moon and Earth, in order to be considered a supermoon.
We just passed a series of three full supermoons, one in December 2017 and two in January 2018. Of these, the January 1 supermoon was the closest and largest. Thus it was the closest and largest full supermoon of 2018.
Still to come in 2018 … a series of new moon supermoons will occur when the new moon closely pair ups with perigee on June 13, July 13 and August 11.
