The Equinox, a Remarkable Yearly Phenomenon
As the Earth rotates around its axis and orbits the Sun, on September 22 this year, the Sun will directly shine upon the Equator. This yearly phenomenon is dubbed “the Equinox”. Actually, there are two equinoxes per year, one in March announcing the beginning of Spring and one in September, announcing the beginning of the Fall.
Equal Night and Day
On the equinox, some say that the length of night and day is exactly the same. Day and night are each 12 hours in every country all over the world. This is why it’s called an “equinox,” which in Latin means “equal night”. However, while many believe it, it is not entirely true.
Equinoxes Don’t Last the Entire Day
An Equinox is not day-long events, even though many celebrate it all day. Actually, it occurs at the precise moment when the Sun crosses the celestial equator. It is an imaginary line just on the Earth’s Equator. During this moment, Earth’s axis is not tilted in any way in relation to the Sun.
Balancing an Egg on Its End
You certainly can balance an egg on its end on the day of the Equinox. But you can also do it on any other day of the year. Some believe that the gravitational force between the Earth and the Sun changes on the Equinox. This allows for this balance to happen. This is also not very scientifically accurate.
