Our Friendly Skies - September 2013

September 04, 2013|By CHRIS KOPKO/William Brish Planetarium and ANDY SMETZER/Tristate Astronomers

Another interesting astronomical occurrence will happen as it does every September, as Sept. 22 marks the first day of fall, or the autumnal equinox, in the northern hemisphere.  This is the point in the earth’s orbit when the sun will be directly overhead at mid-day for all points along the equator.

The seasons change throughout the year due to the revolution of the earth around the sun and the tilt of the earth on its axis.  For more information, check out Astronomy Cast episode 282 on Seasons, found on iTunes or AstronomyCast.com.
