The Wolf Moon is part of a "trilogy" which started with December's Cold Moon and will end on January 31st when a third supermoon will also feature a total lunar eclipse which could make the moon appear red. These sites include a few areas in eastern Asia and eastern Australia, where people will not see the first full moon until 2 January. The first moon of the New Year, the wolf moon, is named after the idea that wolves howl at the moon. The moon will be 223,068 miles, 358,994 in km from Earth.
As a refresher, a supermoon is when a full moon occurs during the moon's closest distance to Earth in its elliptical orbit, which is called its perigee.
There will be another supermoon on January 31 which will also be a total lunar eclipse, and what is termed a Blue Moon as it is the second full moon in a month. This isn't as unusual as the saying "once in a blue moon" might imply: Two full moons typically occur in the same month every two and a half years.
In this case, the whole event is made even a bit more special by the fact that this supermoon is one of three occurring right in a row. The final installment of the supermoon series will kick off on January 31, which will be "extra special", NASA says.
"About twice each year, a full Moon lines up perfectly with the Earth and Sun such that Earth's shadow totally blocks the Sun's light, which would normally reflect off the Moon", NASA said.
In 2018 there will be two Blue Moons - one in January and one in March, February being left out without a full moon. For the viewers of 31 January lunar eclipse, from some places, this will not be entirely visible because it starts near moonrise and is only visible on Earth's night side.
So the moon won't be as bright, but it will "take on an eerie, fainter-than-normal glow", NASA says, and could take on a "reddish hue". According to Space.com, the sky above will be putting on a rare and glorious show of its own over New Year's Day and throughout the month of January with a super blue blood moon you just have to see.
