The reason behind it has to do with the pretty, little planet called Venus. She will be entering her rare retrograde phase on July 25 th, 2015. Astrologically, a Venus Retrograde period is one of the most important times for matters of love. It happens every 18 months to two years and every time Venus does her backwards dance, relationships end up being the topic on everyoneâs minds. Karma also plays into this period, which makes it all the more special.
Retrograde motions arise from the combined motions of the planets and the Earth. Copernicus reasoned that planets further away from the sun would move more slowly than closer ones. As a faster planet overtakes the Earth in their rotations, its motion against the stars, as seen from the Earth, reverses.
