Mercury's Perihelion and Aphelion
After Pluto, Mercury has the most elliptical orbit of any planet in the solar system.

As with all the other planetary distances that involve a
relationship in the form ½ ( Öx + y ), the same relationships
exist in the orbit of Mercury:

Again, Solar Geometry explains the orbits of the solar
system with a relationship that appears again and again.
This results in the following Solar Geometry, show the aphelion (A), mean
(Mercury) and perihelion (P) of Mercury's orbit in relation to the Sun. Note that the
perihelion is half way between the mean orbital distance of 1 and radius of the square,
which is the square root of 2.
