The hour does not recognize the moon
Hu Zuo Bai Yu Pan
Throughout history
People have many imaginations about the moon
According to media reports
At 2am on August 2nd
Staging the first super moon of the year
In recent years, the supermoon has become a popular celestial phenomenon
But it's actually not particularly rare
Zheng Jie, assistant researcher of the National Astronomical Observatory of the Chinese Academy of Sciences, said
The moon is the only natural satellite on Earth
It is also the closest natural celestial body to Earth
Many celestial phenomena are related to the moon
Typical ones are solar and lunar eclipses
Strictly speaking, the "super moon"
It's not an astronomical term
Forming the "Super Moon"
Two basic conditions need to be met
One is "closest", and the other is "roundest"
The orbit of the moon around the Earth is elliptical in shape
When it reaches perigee
Viewing the Moon on Earth
Usually, the apparent diameter will reach its maximum
If it happens to be a full moon at this time
That's usually called the "super moon"
Due to the period of the moon passing through perigee
There is a time difference between the period of phase change and the lunar phase change
The full moon appears about one or two days before and after perigee
It can be called the "super moon"
Therefore, the "super moon"
It can be simply referred to as the "perigee full moon"
The full moon at perigee is greater than apogee
Its visual diameter should be 14% larger
Approximately 30% larger visual area
At this time, the moon looks big and round
Interestingly
When the moon reaches apogee
If it happens to coincide with the "full moon"
Also known as Super Little Moon
The Night When the Super Moon Appears
Under sunny or slightly cloudy weather conditions
Choose a higher and more open place
You can watch the moon with the naked eye
Regular binoculars can also be used
Or observe with a single telescope
When the moon is just rising or about to set
It's a good time to admire the moon
Against the backdrop of ground reference objects
A bright moon, appearing magnificent and unparalleled
If due to weather or other reasons
I won't be able to enjoy the super moon this time
By the end of August, there will be another chance
Based on existing data
There will be two super moons in August this year
The next full moon will be on August 31st
"Super Moon" is not uncommon
But it appears twice within a month
Very rare!
