What it is and why it is important

On Sunday night, a spectacular super moon will rise above the horizon.

Even if you're not the type that pays much attention to lunar activities, after all, the Earth is already functioning as it is, this is one of those astronomical events that will draw the attention of even the most grumpy among us.

What makes this particular moon "super" is quite simple. According to NASA, Sunday's moon will be up to 16% brighter and, in its largest dimension, up to 7% larger than usual, thanks to the shape of the moon's orbit, which is not perfectly circular but elliptical. The apogee is the other end of the orbit of the moon; the perigee is the closest end of the lunar orbit.

Full moons may occur at any point in the elliptical orbit of the moon, but when the full moon occurs just at the perigee, the moon appears larger and brighter, what astronomers call the super moon It is also important to remember that the distance of the moon from Earth can vary from 226,000 to 252,000 miles from Earth, a variability that is longer than the circumference of the Earth.

This supermoon, often referred to as the "cold moon" in the Northern Hemisphere, an indicator that winter is here, will be visible on Sunday morning when the sun rises at 10:47 a.m. ITS T. But the best time to see it will be in the early hours of Monday morning at 4 a.m. EST, when it will be more visible. That said, if getting up early in a cold December Monday morning does not appeal to you, the super moon will also be visible at night. A difference of a few percentage points in brightness and light may seem to shrug, but the fact that the moon is close to Earth will magnify its visual power.

If the total solar eclipse of this year was an indicator, the supermoon could be the harbinger of moments of beautiful and astonished silence and amazement. At a time when we are stuck to the constant and mysterious glow of our digital lives and we are constantly caught with news that provokes anxiety, the opportunity to stretch our necks and direct our gaze to the sky, to what our ancestors looked at while they explored to our young people, an intact world, will be, well, nice. It is not as rare as a total solar eclipse, and it is not so brief and fleeting, but its infrequent appearance and beauty is a magnificent and timely reminder that the universe possesses secrets that go beyond the legacy of daily life on Earth. .

NASA has made sure to inform us that the usual lunar conspiracies are underway, and totally wrong. "A supermoon will not cause extreme floods, earthquakes, fires, volcanic eruptions, severe weather or tsunamis, despite what the incorrect and unscientific speculators may suggest," they warned.

If you live in an area that clouds up annoyingly during the night of the first and last super moon of 2017, do not worry: you can still see it through a free webcast of the Virtual Telescope Project. Time is also on your side: Sunday's super moon is the first of a set of three supermodels that will shine on Earth. The next two full moons, in January and February 2018, will also be supermodels. It may be a cold winter, but the moon will be consistently, amazingly bright.
