The Supermoon approaches the Earth tonight and full of spectacular phenomenon.what does it portrays for you.This year, the full moons of October, November and December all take place when the moon is at its closest point of approach in its orbit around Earth — a so-called supermoon.
The Supermoon on November 14, 2016, will be the closest a Full Moon has been to Earth since january 26, 1948. The next time a Full Moon is even closer to Earth will be on November 24, 2034 (dates based on UTC time).
The most spectacular supermoon since 1948 will light up the sky, appearing 14 per cent bigger and 30 per cent brighter than usual.
The event on Monday November 14 – described as “undeniably beautiful” by American space agency Nasa – is the result of the moon coming closer to Earth than it has done for 69 years.
Nothing will match it until the moon makes a similar approach on November 25 2034.
At 11.23am UK time on Monday, the gap between the Earth and the moon will close to its shortest point, known as “perigee” – a distance of 221,525 miles (356,510 km).
Sky watchers in the UK will have to wait a little longer before the full moon emerges in all its glory shortly before 5pm.
What is the SuperMoon
Super moon is not an official term. It was first coined by an astrologer, Richard Nolle, in 1979. He defined it as ‘a New or a Full Moon that occurs when the Moon is at or near (within 90% of) its closest approach to Earth in its orbit’. It is not clear why he chose the 90% cut off in his definition.
There are no official rules as to how close or far the Moon must be to qualify as a Supermoon or a Micro Moon. Different outlets use different definitions. Due to this, a Full Moon classified as a Supermoon by one source may not qualify as a Super Full Moon by another.
Perigee and Apogee
The Moon’s orbit around Earth is not a perfect circle, but elliptical, with one side closer to Earth than the other.
As a result of the Moon’s elliptical orbit, the distance between the moon and earth varies throughout the month and the year. On average the distance is about 382,900 kilometers (238,000 miles).
The point on the Moon’s orbit closest to Earth is called the perigee and the point farthest away is the apoee.
A Super Full Moon looks larger.
When a Full Moon coincides with its closest approach to Earth, it is called a Super Full Moon. A New Moon that takes places when the Moon is around its perigee is known as a Super New Moon.
The last time the moon sailed this close to Earth was on Jan. 26, 1948, when it came 30 miles closer. The next time won’t be until Nov. 24, 2034, when the distance between the two bodies will be 40 miles less.
