The Not-So-Super but still pretty neat-Moon



Last night was supposedly the night of a rare supermoon, and, having been a fan of fantasy and sci-fi for a long time, a part of my mind was awed by the prospect of some kind of astronomical collision, tidal waves or maybe Iron Skies was right and the Nazi's really were living on the moon. Unfortunately, there is also apart of my head that buries itself into the real world and had the more accurate answer.


Turns out its when the moon appears far larger than normal in the sky. Though not an increase of epic proportions, its still noticeable to the eye. Or at least would be if there wasn't a wall of cloud in the way, which there was last night.


It also turns out that it does this due to the fact that most orbits in the universe don't occur in perfect circles, but in elliptical paths, meaning that at set times the Moon is closer to the Earth than others. But of course the Moon orbits once every month or so, so surely this occurrence isn't so 'Super'. Well yes and no, for a Supermoon also has to be a full moon, and as the moons path isn't identical at each orbit, then the two variables don't always meet, leading to a fairly rare event in a Supermoon
