The Fall Equinox arrives this Tuesday at 9:30 a.m. ET (1:30 pm UTC).
Although not the best time to balance eggs (that’s the story of older wives), the Northern Hemisphere has autumn, cold temperatures, and short days that make up about 90 percent of the Earth’s population.
For the Southern Hemisphere, it indicates the opposite: warm weather and spring.

To explain what is going on with equilibrium, James O’Donoghue, A planetary scientist from the Japan Aerospace Exploration Agency, created an animation that sums up nicely their relationship with the workings of these occasions.

The ions and the equator are the products of the Earth’s axial tilt: the degree to which the planet bends relative to the Sun.
The axis around which the earth spins is not directly up and down – it is closed about 23.5 degrees. Because of this, different parts of the earth are exposed to more or less sunlight as the planet revolves around the sun. That’s why we have asons tuo.
There is also a reason why you experience the Northern and Southern Hemispheres at opposite times: during the winter in the Northern Hemisphere, the Southern Hemisphere tends to lean more towards the Sun, and vice versa.
In the meantime, the earth is constantly spinning, which also keeps its heat just right – like a planet-shaped rotisserie chicken spitting out.
The most dramatic effect of axial tilt comes during the solstice, as it is two days when one side of the planet is tilted too far away from the sun and the other side is closest. On December 21, the Northern Hemisphere receives less than nine hours of daylight, while the Southern Hemisphere receives more than 15.
During the summer solstice, O Donogu explained On Twitter, “Sunlight is most intense because it only has to pass through a short column of the atmosphere.” That’s why it usually gets hot during the summer.

The two times of the year when the Earth’s axes are not tilted toward or towards the Sun – the leading sunlight to hit evenly in the Northern and Southern Hemispheres – is equinox. In those days, both sides of the planet experience the same 12 hours of sunlight and darkness.
So if you were to stand straight at the equator at 9:30:30 a.m. on Tuesday, your shadow would be at its absolute minimum. The sun will also appear almost directly overhead.
But the moment without shadows will be fleeting, as the earth revolves around the sun at a speed of about 66,600 miles (107,182 km / h).
