This is Wednesday September 22 We change the seasons. Today it will leave Mexico in the summer of 2021 and embark on The autumn, is the season of the year when dry leaves fall and orange, brown and ocher landscapes dominate.

According to a report by the National Institute of Astrophysics, Optics, and Electronics (INAOE) The fall will last 89 days, 20 hours and 38 minutes. It ends on Tuesday, December 21, to make way for winter.

The entrance to the new station occurs because on Wednesday it will be held in September equinox, at 2:21 pm This astronomical event occurs when the sun is located at the level of the Earth’s equator, that is, at the height of the imaginary line that separates the northern and southern hemispheres.

In addition, during this phenomenon, the axis of our planet is not tilted towards or away from the star, but rather remains at a right angle. As NASA explains, this makes the separator – the vertical line that divides day and night – through the north and south poles. Therefore, all corners of our world receive during this day The same hours of light as darkness.

“The equinoxes are the time in the Earth’s orbit when the tilt of our planet’s axis is not directed toward or away from the sun, but rather sideways. Then the Earth’s axis is perpendicular to the direction of the sun,” the space agency explains on its website.

Also, if we consider the position of our planet relative to the Sun, it is located at right angles.

Our planet reaches this specific position only twice a year: in March (between 19 and 20) and in September (between 21 and 24).

“This only happens twice in the Earth’s annual journey around the sun. And for the rest of the year, the star shines unevenly in Northern and Southern hemispheres. This is because the Earth’s axis is tilted with respect to the plane of the Earth and the Sun. But on these special days, the spring and autumn equinoxes, the star shines equally in both the north and the south,” adds the US space agency.

With the spring equinox of September, Autumn begins in the northern hemisphere, While in the south spring begins. The new season will bring more hours of darkness to Mexico.

“From the autumnal equinox to early spring, the night hours will last longer than daylight as the sun travels a shorter arc across the sky each day,” NASA explains.

Here we see how the separator, the vertical line that divides day and night, crosses the North Pole and the South Pole.  For this reason, all regions of the planet receive 12 hours of light and 12 hours of darkness, a fact that only occurs during the vernal and autumnal equinoxes (Photo: Pixabay)

During this time we will be able to observe some wonderful astronomical events, such as the partial lunar eclipse that will occur in November. Plus, on October 31, we’ll turn back the clock and start winter time. Here are some of the most notable astronomical events:

* October 8: meteor shower max the Dragon. We can see about 20 meteors per hour.

* October 20: full moon.

* October 21: Starfall Max Orionids. Up to 15 meteors can be observed per hour.

October 31: start in winter time.

* 3 November: Comet 67P/Churyumov-Gerasimenko will be seen between 00:11 and 05:40 CMT. It will appear in the direction of the constellation Gemini, in the northeastern part of the celestial sphere.

November 4th: Uranus in opposition At the perihelion point – the lowest distance from the earth -. It will be visible to the naked eye in a very dark sky.

* November 5th: meteor shower max South of Torres. Up to five meteors can be seen per hour.

* November 12: meteor shower max North Torres. During the peak, up to five meteors per hour will cross the sky.

* November 17: meteor shower max Leonidas. There will be up to 20 meteors per hour.

* November 19: Partial lunar eclipse. The maximum will be at 03:04 CMT. It will be visible between 00:02 and 06:04, including the period when the satellite enters the gloom of the Earth.

* November 19: full moon It will be approximately at its zenith – the point of its orbit farthest from our planet.

* December 2nd: meteor shower max Phoenicians. The rate at which it can be observed will be variable and will be between 0 and 100 meteors per hour.

December 4th: total solar eclipse that will not be visible from Mexico.

* December 7: meteor shower peak Puppid. At least 10 meteors can be seen per hour.
