Over the "Super Moon" in the 68 years the "big misunderstanding"

Greater than usual, super moon bright moon decorate the night sky. November 14, 2016 in the ostensibly "super Moon of 68 years" can be seen, or would not than many people are looking forward from now.

　

However, think back and try and also two years ago last year became a hot topic of "Super Moon is seen", it should not be actually less people you eyes. What is a "68 years", it would be to some people was wondering about.

When the expression such as "hundreds of years" is used, it tends to give the impression that the super Moon itself is extremely rare. But, in fact, super moon is happening to every one to two years, not very rare phenomenon. And say of what is the first time in 68 years, it's of a "distance of the Earth and the moon."

　

Because orbit the moon around the circumference of the Earth is elliptical, the moon will move closer to the Earth from the usual, if you are or Tonoi, the distance is varied between from about 350,000 6000㎞ of about 400,000 6000㎞ there. What is called the super moon is the moon became full moon at the timing just close to the earth.

　

Super Moon of this year November 14 approaches to the place of 350,000 6520.2㎞ from the earth. This as the full moon is approaching in the sense that it is since 68 years ago on January 26, 1948 (about 350,000 6490.6㎞), I mean that is referred to as the "68 years". Super Moon of the still fresh in our minds September 28, 2015 is approximately 350,000 6900㎞, those of August 11, 2014 was about 350,000 7000㎞, certainly is remarkably close this time.

　

So, compared to the Super Moon last year and two years ago this year, how much greater look of either. Unfortunately, the apparent size is not almost the same, the difference is that he's a less than 1%. Spokesman of the National Astronomical Observatory of Japan said.

"To begin with I quite hard to feel the difference of the full moon size. Although close to the full moon is 350,000 6520.2㎞ of this year on November 14, this distance is called the" geocentric distance ", Earth It refers to the distance from the center to the center of the month. since we have seen the moon from the surface of the Earth, in when it is in the zenith and when the moon is in the horizon, the distance of us and the moon will change greatly. It is almost the same as the geocentric distance when in the horizon, the Earth's radius (about 6400㎞) when in the zenith minute, we are close to a month. that is the month when it is in the zenith is of such should see the greatest "

　

But what will not be felt towards the moon near the horizon is large. According to the person in charge, this is thing of to be due to the illusion of eyes, we also approached about 6400㎞ also to the moon, we can not accurately grasp the change in the size.

"Full moon of this year November 14 days, about 30km far than those of 68 years ago, about 500km closer than last year or two years ago. However, considering the size of a radius of Earth of about 6400㎞, like almost no notice 's the difference. that is the phrase "a few tens of years", although there is in fact, so to speak, like a play on words, little sense will say that there is no "(supra National Astronomical Observatory of Japan spokesman)

　

Super Moon It can not very "Super" referred. In this way, in the background that valuable of the Super Moon is overemphasized, there will be the attitude of the media that you want to the topic creation. It's also true that there is a thing to add color to people's lives, but, if the misunderstanding, ought been corrected.

　

Also another, there is a surprising fact about the Super Moon. I there is no clear definition in the Super Moon. Spokesman of the National Astronomical Observatory of Japan do this will be explained.

"It seems NASA has begun to use the word super Moon from a few years ago, but this word is not in the formal terms of astronomy, National Astronomical Observatory of Japan does not use. This is a problem is" the next super moon when I became a story that someday. "because of the full moon was close to 350,000 6520.2㎞ Although it is called super moon, there is no standard of whether referred to as how close became After Super Moon this year, the next super moon There's is "can not answer that one day

　

might have resulted discourage the people who had been looking forward to the Super Moon. But, the person in charge is this also says.

Including "night with a full moon, the Japanese there was a custom to watch the full moon for a long time. However, this busy modern, have fewer opportunities to admire the moon and calm especially among young people. To represent over the Super Moon Although there are certainly, Whatever the reason, many people are believe that the great become prime views of the moon, " but can not be the next super moon answer whether it is time, this year November 14 2034 November 24, after 18 years of full moon is closer to Earth than the day. Since there is no change in it is still valuable, or would invite you Kyoji in the fall of the moon.
