Supermoon, 19th March 2011 (Phenixsport)On Monday 14th November the Moon will arrive at its closest point, its perigee, to the Earth in 2016: 356,508 kilometres (221,524 miles) away. This distance—measured from the centre of the Earth to the centre of the Moon—is just 137 kilometres (85 miles) away from being the Moon's closest possible distance from Earth. It becomes a full moon 2 hours 37 minutes after the precise moment of perigee, at 1.52 p.m. GMT (8.52 a.m. EST) . When a full moon coincides, or nearly coincides, with the moon being at its closest point to Earth on its orbit, it is called a “supermoon”, or, more correctly, a “perigee full moon”. What makes November’s event special is that will be the closest full moon since 26th January 1948, just under 69 years ago. It won’t be this close again until November 2034.
Average moon and supermoon compared (Marcoaliaslama)There are between four and six supermoons every year on average. The difference between this unusually big supermoon and other supermoons (such as the one on 16th October or the next one on the 14th December), will, however, be almost impossible for the eye to detect. And although supermoons can appear up to 30% brighter and 14% larger than full moons when the Moon is at its apogee (its farthest point from Earth), the November supermoon will not even look that different to other ordinary full moons.
