The complete Wolf Supermoon of three January 2026 goes to place in one of many brightest appearances of which our Moon is succesful, and it is all all the way down to a rare set of serendipitous circumstances.
A full supermoon takes place when the complete part of the Moon coincides with perigee – the purpose within the Moon’s orbit at which it’s closest to Earth.
The perigee of January 3 will convey the complete Moon to a distance of 362,312 kilometers (225,130 miles) from Earth, giving it an obvious measurement and brightness enhance of about 14 and 30 p.c, respectively, in comparison with its most distant level.

That distance is a little bit farther than the Chilly Supermoon of 4 December 2025, however the brightness kick from one other well timed characteristic will possible make up for the dearth of distance.
This 12 months’s Wolf Supermoon may even fall simply hours from a perihelion – the purpose in Earth’s orbit at which it’s closest to the Solar, about 3.4 p.c nearer than its farthest level. This means only a tiny bit extra daylight reaches the Earth-Moon system, giving one other brightness enhance.
On condition that chilly air has much less humidity than heat air, making the sky extra clear, January 3 may current an ideal alternative to go moongazing within the Northern Hemisphere, clear skies permitting – no particular tools required, simply your individual two eyes and a snuggly blanket.
Supermoons are a pure consequence of the form of the lunar orbit round Earth. It isn’t completely spherical, however barely oval; because of this, there are factors alongside the Moon’s path at which it’s a contact nearer or farther than its common distance of 384,400 kilometers (238,855 miles) from Earth.

The purpose at which it’s closest to Earth is called a perigee, of which there are round 13 a 12 months, give or take.
The lunar orbit precesses, which means its oval form would not observe the identical orientation each time, so the timing of the perigees will not be precisely aligned with the lunar cycle. There are fewer supermoons than perigees, as a result of it is solely when the perigee happens on a full or new Moon that we seek advice from it as a supermoon.
Curiously, the perigee distance additionally modifications fairly a bit because of different contributing components, such because the gravitational tug of the Solar and the shifting, long-term relationship between Earth and the Moon.
In the meantime, perihelion is an identical phenomenon on a bigger scale in Earth’s orbit with the Solar. It happens yearly in early January, across the third of the month, bringing our homeworld to a distance of 147,099,900 kilometers (91,403,640 miles) from the Solar, in comparison with its common distance of 149.6 million kilometers.
This may improve the quantity of photo voltaic power reaching our planet and its Moon, giving the complete Moon one other brightness enhance of about 6.5 p.c in comparison with aphelion, essentially the most distant level within the Earth-Solar orbit.
It is known as the Wolf Supermoon as a result of January’s full Moon is called the Wolf Moon. It is simply that this 12 months’s Wolf Moon goes to be further particular, coinciding with two different celestial occasions for a uncommon triple cosmic deal with… dare we even say… a Three Wolf Moon?
It is also the final full supermoon we’ll see till 24 November 2026, so get on the market and profit from it.
