# Dance of the Planets

Another intriguing fact is the ratio between the Earth’s outer orbit and Venus’s inner orbit is given by a square.

The planets in the heavens move in exquisite orbital patterns, dancing to the Music of the Cosmos.  There is more mathematical and geometric harmony than we realize.   The idea for this article is from a book Larry Pesavento shared with me.  The book, ‘A Little Book of Coincidence’ by John Martineau, illustrates the orbital patterns and several of their geometrical relationships.  .

Take the orbits of any two planets and draw a line between the two planet positions every few days.  Because the inner planet orbits faster than the outer planet, interesting patterns evolve.  Each planetary pairing has its own unique dance rhythm.  For example, the Earth-Venus dance returns to the original starting position after eight Earth years.  Eight Earth years equals thirteen Venus years.  Note that 8 and 13 are members of the Fibonacci number series.

Earth:     8 years * 365.256 days/year  =  2,922.05 days

Venus:  13 years * 224.701 days/year  =  2,921.11 days (ie. 99.9%)

Watching the Earth-Venus dance for eight years creates this beautiful five-petal flower with the Sun at the center.  (5 is another Fibonacci number.)

Does this take into account the elliptical nature of planetary orbits? Especially for Mars.

Someone’s been playing with a Spirograph! 🙂
