“Blue moon”: Why tomorrow’s full moon is so special

October will have a second full moon tomorrow, the last day of the month.

The first full moon of October had occurred earlier this month. It is the first time since March 2018 that two full moons occur in one month.

Double full moon in October
Officially, according to NASA, tomorrow’s full moon will occur at 15:49 Greek time. The phenomenon of double full moon in the same month occurs on average every 2.7 years. The next time will be in August 2023. For those peoples who celebrate Halloween on October 31, the double full moon, which in the USA since the 1940s has been called the ” sad or blue moon ” (“blue moon”), has an additional peculiarity. .

During the second full moon of October, the moon will be at the farthest point of its elliptical orbit from the Earth (lunar apogee), at a distance of about 406,400 kilometers (the average distance between the Earth and the Moon is about 384,500 km). It is therefore a “micro-moon”, the opposite of the “super-moon”, when the moon has approached the Earth very (peripherally).
