The lunar orbit of Earth follows a 29-day cycle. The blue moon, like the one on January 31, occurs when there are two full moons in a calendar month.
The moon will also be close to Earth during this time, meaning it will be brighter than normal. This is called a supermoon.
When the moon passes through the Earth's shadow during the Jan. 31 lunar eclipse it will appear red. This creates the blood moon.
Most of Asia, Australasia and the northwestern America will be able to see this super blue blood moon, while much of South America, Africa and West Europe will not. The rest of the world will be able to see it partially depending on their location.
