Video Two: The Orbital Grid
This is the second step of Heliocentric Astrology: the orbital grid.
We base our grid on the easiest measurement, the Astronomical Unit. This is the radius; the distance from the sun to the earth in a straight line.
These are the distances, in astronomical units, of the first eight planets.
Mercury: .387
Venus: .723
Earth: 1
Mars: 1.52
Jupiter: 5.20
Saturn: 9.52
Uranus: 19.20
Neptune: 30.08
For this model, the true scale was only used for the first four planets. The outer planets are condensed.
A Polar Point is the ecliptic longitude position that is 180 degrees from a planet’s position. For this model, only the Polar Point of Earth is used.
These are the orbital periods of the first eight planets.
Mercury 88.0 days
Venus 224.7 days
Earth 365.2 days
Mars 687.0 days, 1.88 years
Jupiter 4331 days, 11.85 years
Saturn 29.42 years
Uranus 83.74 years
Neptune 164.73 years
The solar ecliptic degrees that mark the constellation boundaries also track the planetary positions on their orbital paths around the sun.
For example: On March 1st, 2010, Earth was at the ecliptic longitude of 160.27 degrees. This location is inside the constellation section of Leo. On the same day, Venus was at 17.79 which is inside of Pisces.
For the graphics on the Geogebra page, this is our distance scale.
Mercury: .77
Venus: 1.45
Earth: 2
Mars: 3.05
Jupiter: 3.5
Saturn: 4
Uranus: 4.5
Neptune: 5
