This Wednesday, September 22, 2021, autumn begins in the northern hemisphere of planet Earth, while spring begins in the southern hemisphere. Thus, it is of special interest to know what exactly the autumnal equinox is .
The word equinox comes from the Latin words “equi” (equal) and “nox” (night). Therefore, it means that there is the same amount of light during the day and at night.
Simply put, the autumnal equinox occurs when the Sun is exactly on the Earth’s equator, so that the day and night last exactly the same. Our planet rotates on an axis with an inclination of 23.5 degrees with respect to its orbital plane. This means that while the Earth makes its orbit, both hemispheres tilt, so that they are more or less close to the Sun.
This 2021 autumn begins on September 22 and ends on December 21, so it will last exactly 89 days. Well, from this Wednesday, as autumn progresses and winter approaches, the northern hemisphere will tilt farther and farther from the Sun , receiving the sun’s rays at a steeper angle. This explains why the days are getting shorter and the temperatures decrease.
The most surprising curiosities of autumn
A study published in the “Journal of Aging Research” found that babies born during the fall months are more likely to live to be 100 years old. To carry out the ingestion, scientists studied American centenarians born between 1880 and 1895, and found that 30% were born in the fall.
Another curious fact is that in this season of the year it is easier to gain weight due to the lack of vitamin D, which reduces the breakdown of fats. This explains why the lack of sunlight makes it easier for us to gain weight.
