The moon will appear about 16 percent brighter and 7 percent larger than normal, according to astronomers.
There has been other reported times this year where the moon has been closer to Earth, however it wasn't considered a Supermoon because it didn't land on a day where it was a full moon.
The average distance between the moon and earth is 3,84,000 km, but at perigee, it is 3,56,000 km and at apogee, it will be 4,06,300 km. That kind of full moon won't be seen again from Earth until 2034, according to NASA. The Moon's orbit around our planet is tilted so it usually falls above or below the shadow of the Earth. Hence, for those in the Northern hemisphere, it is a cold supermoon.
The last full moon of 2017 will appear especially plump and vibrant in the night sky on Sunday (Monday NZ time). Even so, the supermoon is still worth viewing.
The difference is noticeable for close observers - particularly if the moon is near the horizon, where it can be compared with terrestrial landmarks.
Christmas parade set Monday, 100 entries expected downtown
Young and old alike lined the streets to watch dozens of floats, marching bands and, of course, a special visit from Santa Claus. The Gillette Masonic Lodge also will offer free hot chocolate and hot cider from 4-6 p.m. for parade-goers at the lodge, 407 S.
Astrologer Richard Nolle defined a supermoon in 1979, but the term has really taken off in the past few years. This is known as the moon illusion and the moon hasn't grown; it's a trick your eyes are playing on you.
Just to be clear, the supermoon is only the moon-there will be no eclipse and no colors.
This optical illusion also occurs when watching the supermoon immediately after sunset (or before sunrise).
"If you stretch out your arm at full length, and stretch out your thumb, and compare the size of the full moon in the sky to the size of your thumb, you'll notice the width of the full moon compared to the size of your thumb; you can put four full moons across the width of your thumb".
Mark your calendars: a series of three supermoons will appear on the celestial stage on December 3, 2017, January 1, 2018, and January 31, 2018. "But it's another great chance to watch the Moon".
