Astronomy for Astrologers
The earth is floating in space, in the plane of its orbit (of
course), with its pole tilted toward zero-degrees of the
zodiac sign Cancer. It rotates (in this diagram) in a
counter-clockwise motion. Therefore, the birth place
(blue dot here), is turning into or toward the dark half of
the earth, which is night. The latitude (both
geographically and celestially) is 40-degrees north—this
is marked on the diagram by the blue oval.
