The third and last supermoon for the year will take place on the night of Thursday, June 24.
It was preceded by the supermoon of April 27 and May 26.
Once again the moon will be closer to the Earth and the full moon will appear larger than usual.
“Different publications use slightly different thresholds for deciding when a full moon is close enough to the Earth to qualify as a supermoon,” NASA said.
“Because the orbit of the moon is not a perfect circle, the moon is sometimes closer to the Earth than at other times during its orbit.”
On average, supermoons appear about 7% bigger and about 15% brighter than a typical full moon.
This full moon was traditionally known as the “Strawberry Moon” to the American Indians, because it falls at a time when the ripe strawberries are being harvested.
As the moon’s elliptical orbit around the Earth fluctuates the distance between the two bodies, a supermoon occurs when the full moon coincides in time with a very close approach to the Moon.
The Earth-Moon distance ranges from 406,712 kilometres to 356,445 kilometres.
When the full moon occurs near the orbit, then it is considered a super-moon, super-moon or super-full moon, terms that are not astronomical.
The term, according to the US Space Agency (NASA) , was invented by the astrologer Richard Nolle in 1979.
A full moon at the periphery looks up to 14% larger and 30% brighter than a full moon at the apogee.
Also a super-full moon is about 7% larger and 15% brighter than an average full moon.
The low arc of the June full moon across the sky means moonlight must travel through more of the Earth’s atmosphere, which often gives it an orange or yellow tint.
The strawberry moon is also called “hot moon” because it rises right around the beginning of summer.
In Europe, alternative names include the honey moon, the mead moon or the rose moon.
