Venus's Orbit and Its Harmonic Relation to Earth

"Venus rotates extremely slowly on her own axis in the opposite direction to most rotations in the solar system. Her day is precisely two-thirds of an Earth year, a musical fifth. This exactly harmonizes. . . so that every time Venus and Earth kiss, Venus does so with the same face looking at the Earth." Eight Earth years equals, exactly, thirteen Venus years, the five kisses between them crafting a perfect pentagon, carved out of space. The numbers 5, 8, and 13 belong to the Fibonacci sequence, defining Phi.

Every 243 years, Venus passes between the Earth and the Sun twice in eight years-- a pair of "Venus transits," visible to the naked eye. In our own time, an initial transit occurred on June 8, 2004, to be matched by a second on June 6, 2012. The Venus transits also reflect the harmonic relation between the two orbits--in those 243 Earth years, exactly 365 Venus days will have passed.
