Astronomy fans will have the chance to witness an exceptional phenomenon this night from Monday July 3 to Tuesday July 4. They will indeed be able to observe a supermoon in the sky, a rare phenomenon that occurs three or four times a year maximum.
Note that this supermoon – scientifically called perigee-syzygy – has been baptized “super deer moon”. The reason is simple: it appears in July, the time of year when male deer spread their antlers.
As for the scientific name perigee-syzygy, it refers to the combination of two simultaneous phenomena. Syzygy is that moment of full moon during which the moon and the sun are opposite each other with respect to the Earth, in the center, allowing the sun to illuminate the moon in a particular way. . Perigee is when the moon comes closest to Earth in its orbit. The Moon’s orbit being elliptical, the Earth-Moon distance is indeed variable. At apogee, the point where the Moon is furthest away, the satellite is 406,000 km from Earth. Conversely, at perigee, it is 356,500 km from us. This Monday evening, the actual distance to the nearest will be 361,934 km.
Other full moons are expected this summer: August 1 (“super sturgeon moon”), August 31 (“super blue moon”) and September 29 (“super harvest moon”). The most “remarkable” will be the super blue moon on August 31. The latter will be located 357,344 km from the Earth.
It should also be noted that to properly observe the phenomenon this Monday evening, it will be necessary to wait for sunset and to favor a place without light pollution.
