The 45th parallel south is a circle of latitude that is 45 degrees south of the Earth's equatorial plane.
It is the line that marks the theoretical halfway point between the equator and the South Pole. (The true halfway point is 16.2 kilometres (10.1 mi) south of this parallel because the Earth is not a perfect sphere but bulges at the equator and is flattened at the poles.)
Unlike its northern counterpart it passes mostly over open ocean. It crosses the Atlantic Ocean, the Indian Ocean, Australasia, the Pacific Ocean and South America.
At this latitude the sun is visible for 15 hours, 37 minutes during the December solstice and 8 hours, 46 minutes during the June solstice.

“The beginnings of altruism can be seen in children as early as the age of two. How then can we be so concerned that they count by the age of three, read by four, and walk with their hands across the overhead parallel bars by five, and not be concerned that they act with kindness to others?”
—Neil Kurshan (20th century)
