Super Flower Moon is the last in a series of four supermoons in 2020. The full moon in May is known as the Flower Moon. Since this full moon is also a supermoon, it is being referred to as the Super Flower Moon. According to the Farmer’s Almanac, the Full Moon of May is called Flower Moon because, in most areas, flowers are abundant at this time of the year. It is also called Full Corn Planting Moon as well as the Milk Moon.
“Supermoon”, the term, was coined by the astrologer Richard Nolle in 1979. It refers to either a new or full moon that occurs within 90 per cent of perigee — or when it is closest to the Earth in its orbit. Since the moon has been at perigee for the last three months, this is the final supermoon appearance in 2020. In other words, when the Full Moon or the New Moon occurs during the Moon’s closest approach to the Earth, it is termed as the Super Moon.
The full moon arrives just 32 hours after the moon reached perigee or the closest approach to Earth in its orbit. That makes this a “supermoon,” according to NASA.
