A supermoon occurs when a full moon coincides with the point in orbit in which the moon is closest to Earth. Supermoons look a bit brighter and closer to Earth than average full moons, though it can be hard to spot the differences without a telescope.
Unusual astronomical phenomenon called the Supermoon, or perigee moon.The orbit of the moon around the Earth in form is not a ideal circle, and a few stretches. That supermoon will also be the second full moon of the month, making it a "super blue moon".
Each month the moon rotates around the earth in an ellipse rather than a flawless circle. Hence, for those in the Northern hemisphere, it is a cold supermoon.More news: Tiger Woods Cards Opening Round 69 at Hero World Challenge

If you don't think you'll want to leave the comfort of your own home to view the celestial event, there will be two livestreams of the supermoon.
A supermoon occurs when there is a full moon at or near the point where the moon reaches perigee. But any time you catch a full Moon as it rises or sets, while it's suspended low on the horizon beaming through the silhouettes of trees or buildings, its apparent size might make you do a double-take.
This optical illusion also occurs when watching the supermoon immediately after sunset (or before sunrise).More news: Medical experts: Flu season may be a bad one
Considering that a full moon can be covered with a fingernail, even a 7% larger moon may not look that much bigger.
