It’s a phenomenon that only happens once every 10 or 20 years, according to NASA. Tonight, we will have to observe the sky, more precisely, our natural satellite, because it will turn into a super blue moon.
What is it about?
We’re talking about a blue moon when there are not one but two full moons in the same month. This only happens every two to three years, because there are usually only 12 full moons in a year.
Tonight, in addition to watching the “blue moon”, we will enjoy the “giant moon”, when the moon approaches the Earth in its elliptical orbit, that is, less than 364,000 km from our planet, 20,000 km less than usual.
Tonight, our moon will be brighter and larger, but it will not be “blue” (this name comes from the English expression “blue moon”).
This evening, our moon will be brighter and larger.iStock pictures.
It would be a shame to miss this moment tonight because NASA expects the next “super blue moon” to appear in January 1937.
To monitor it, it is best to stay away from cities and pollution. Amateurs can also take out their binoculars or telescope.
For its part, NASA put it online Frequently Asked Questions For those who should become familiar with the topic.
