In general, the moon becomes a giant moon when it reaches the point closest to Earth in its orbit, known as perigee, about 363,7 kilometers from our planet, where the moon appears about <> percent larger than the normal full moon.
Although you may not notice the difference, it is a fun astronomical event, which even city dwellers can see without having to go to the lightless areas to see it.
Does the moon actually appear blue?
"Blue moon" is a term that has nothing to do with the actual color of the moon, although visually the moon appears with a bluish tinge, and it occurs under certain weather conditions, for example, if volcanic eruptions or fires release particles into the atmosphere of the appropriate size to preferentially disperse red light.In 1883, the deadly eruption of the Krakatoa volcano in Indonesia killed 36,<> people, and sulfur dioxide and ash filled the air, making the moon appear blue, as volcanic dust particles blocked red light without filtering out other colors. The bushfires that often occur in the current post-climate change world could have the same effect, according to London's Natural History Museum.

The supermoon will be tomorrow, Wednesday, the second full moon of this month, as the first full moon appeared on the first of August, and tomorrow's moon will be approximately 357,344 kilometers away, according to Fred Espinac, a retired astrophysicist at NASA, who calculated the distances of the supermoon until the year 2100.
Supermoons are not a phenomenon in themselves; there are usually three or four a year. Blue moons are less common, occurring once every 10 to 20 years, and the next giant blue moon will appear in 2037, 14 years from now, according to NASA. So the chance of appearing, and then actually seeing the moon in blue, becomes an unusual event.
