Sounds like it should be fairly interesting tonight...must remember to look up.
Each month the Moon orbits the Earth in an oval-shaped path, and on December 12 it will move past it around 28,000km closer than average.
The unusual feature is that this will coincide with a full moon, which will make it appear 14 per cent bigger and 30 per cent brighter than most full moons this year, on Friday night.
Astrologists say the next encounter with a moon this close and full will not be until November 14 2016.
To make the sight even more spectacular much of Britain should be treated to a phenomenon known as the Moon illusion.
This is an optical illusion in which the Moon appears larger near the horizon than it does while higher up in the sky.
Psychologists have tried to explain this as a trick of the eye, as the landscape on the horizon appears to make the Moon loom much larger, an effect that disappears as the Moon rises above the horizon.
Another astronomical treat that could be seen over the weekend is the annual Geminid meteor shower, one of the year's best displays of shooting stars.
Up to 100 meteors an hour can fly across the sky. The meteors, which are easy to spot with the naked eye, appear to shoot out from the constellation Gemini, hence their name, but they can be seen all over the sky.
The best chance of seeing them is to look away from the Moon.
