Description
The minimum energy path between two planets is called a Hohmann orbit. It's an ellipse which is tangent to both planet's orbits.
The Earth-Venus synodic period is very close to 8/5 year. The period of an Earth-Venus Hohmann orbit is very close to 4/5 of a year.
This makes a very nice system of Earth to Venus cyclers possible.
Launch windows to catch a cycler would be on the tips of a cosmic 5 pointed star.

I don't think I really understand this image. Couldn't this Hohmann orbit be represented with only two planets? I see the white dots indicate the outer and inner circles to which the orbits of the planets are aligned, so I assume you're using 4 planets to illustrate the cycler events? Would this also work for other planets or only from Earth to Venus?
I'm definitely not well versed in math, so could you explain in a simple way why these cycler events align to 5 symmetrical points? Do the orbits not decay?
