Autumn Equinox September 22, 2016

The term equinox is used by meteorologists to mark the change in seasons in spring and autumn, and occurs when the sun passes directly over the equator, creating a day and night that are the same in length.  The equinox occurs because of the tilt of the Earth in relation to the sun.  The Earth’s tilt is 23.5 degrees relative to the plane of its orbit and means that, although one revolution of the planet takes 24 hours – it’s different depending on the time of year. On the autumnal equinox, the Earth hits the turning point in its orbit where neither the North or the South poles are tilted towards the sun. That means the amount of daylight and night time is the same at all points on the Earth’s surface.
