Blue Micro Moon, 31st October 2020

Do You hear about the idiom "Once in a blue Moon" .

On 31 October 2020 this idiom become true as this saturday's full moon will also be called by the name of Blue Moon.


Every month has a full moon, but because the lunar cycle and the calendar year aren't perfectly synchronized, about every three years we wind up with two full moons in the same calendar month. The revolution period of moon around earth is nearly 29.5 days.


Every month's full moon has its own unique name from old farmers almanac. In the month of October full moon is known as Harvest Moon, but this full moon on 31st will be called as Hunter's Moon.


Here one thing is more intresting that on blue moon the moon isn't actually blue.


An older definition of Blue Moon is that it’s the third of four full moons in a single season. Someday, you might see an actual blue-colored moon.

The term once in a blue moon used to mean something rare.

Can a moon be blue in color?

There’s one kind of blue moon that is still rare. It’s very rare that you would see a blue-colored moon, although unusual sky conditions – certain-sized particles of dust or smoke – can create them.


Blue-colored moons aren’t predictable.


There was a full moon on 1- 2, October 2020. There’s another full moon on October 31. So the october 31 full moon will be called a Blue Moon.


Another interesting fact is that this blue moon is also called blue Micro Moon.
Micromoon is an opposite term of Supermoon on which moon is on its farthest position from earth known as 'apogee'. The size of micromoon is 14% less and 30% less illuminating than Super Moon.

The distance of moon on 31st is 406400 kilometer. On 17th of October moon was on its perigee when itz distance from earth was only 356900 kilometer.
