Scientific Facts About The Fall Equinox

Can you believe six months have already passed? It’s time for the fall equinox baby - let’s recharge our crystals and dust off those cozy flannels! This year the first day of fall lands on September 23, but what does that mean for us?

The fall equinox, also known as the autumnal equinox, is one of two times each year when the sun is directly overhead the equator. This occurs on or around September 22 or 23 in the Northern Hemisphere and March 20 or 21 in the Southern Hemisphere.

Scientific facts about the fall equinox

• The fall equinox marks the beginning of autumn in the Northern Hemisphere and spring in the Southern Hemisphere.
• On the fall equinox, the sun rises due east and sets due west.
• Day and night are approximately equal in length on the fall equinox, but not quite. This is because the sun's disk is not a point, but rather a sphere. As a result, it takes the sun a little longer to set below the horizon on the equinox than it does to rise above it.
• The fall equinox is caused by the Earth's tilted axis. As the Earth orbits the sun, its axis remains tilted at an angle of 23.5 degrees. This means that the Northern Hemisphere is tilted towards the sun in the summer and away from the sun in the winter. On the fall equinox, the Earth's axis is neither tilted towards nor away from the sun, which results in day and night being approximately equal in length.
