equinócio de setembro

 

autumnal equinox

 

 

“on the equinox, night and day are nearly the same all over the world: ~12 hours….( widely accepted, it isn’t entirely true)”

 

 

“On September equinox days the Earth’s axis is neither tilted away nor towards the Sun, but has both northern and southern hemispheres experiencing equal amounts of sunshine.”

 

 

“Seasons are opposite on either side of the Equator, so the equinox in September is also known as the Autumnal (fall)”
