The expression "supermoon" is not a term used by astronomomers. The scientific name for the Moon's closest approach to the Earth is called a "Perigee Full Moon".
Yes on November 14, 2016, the Moon will seem larger than it has appeared for the last 68 years.|
Before you get too enthused about observing this "supermoon", it may be wise to consider this comparison.
If you are an American, you are no doubt familiar with the nickel coin, which has a diameter of .835 inches (21.21 mm).
The Moon, on average, is the size of a nickel observed at a distance of 7.6 feet (2.32 meters).
When observed during this "supermoon", it will be the size of a nickel at 7.14 feet (2.18 meters).
I am certainly not trying to disparage astronomy. Instead, I just don't like the way the media tends to exaggerate news stories.
Nevertheless, the Moon has made the headlines recently because on November 14, 2016 it will display as a "supermoon" appearing larger and brighter than usual. This is not an unusual event and occurs because the Moon's elliptical orbit about the Earth changes its distance from from 357,000 kilometers (perigee) to 406,500 kilometers (apogee).
