There shall not be found among you anyone who burns his son or his
daughter as an offering, anyone who practices divination or tells
fortunes or interprets omen....And I will cut off sorceries from your hand, and you shall have no more tellers of fortunes;
Deuteronomy 18:10/Micah 5:12 ESV
"The basic premise of astrology is the stars and the
planets exert an 
influence over events on Earth.
The stars’ and planets’
exact influence depends on their motions and relative positions, such
as when they appear close together in the sky.
To the informed mind——astrology can’t possibly work.
That’s because these heavenly
bodies are nothing more than agglomerations of rock, dust, or gas.
There
are distant influences from the stars and planets, but they’re called
the gravitational and electromagnetic forces.
The gravitational force
creates an attraction between masses. Electromagnetic forces transmit
light, heat, magnetic attraction, and repulsion.
There is a pull on
Earth due to these bodies’ masses, and we see the light (and, in the
sun’s case, feel the heat) they emit.
That’s it." ePocket
