The Phase Shift Chart here shows data
compiled by Lawrence Edwards over a period of nearly 18 years. Of it,
he said, “Each [yellow] cross gives the phase shift for a species for a season.”
The Heliocentric Line of Position (blue) is the line
joining the Sun and the Centroid of Position (CP) of the principle
bodies of our Solar System. This centroid is concerned only with position,
just pure position, and excludes the Sun itself, and Pluto.
The Centroid of Mass (CM) is the same as the centroid of
position, except that each body-position counts the-mass-of-that-body times
over: that is, if a given body has a mass m units, then the
body's position counts m times over when the centroid comes
to be computed.
The CM is rarely where the CP is.
White or light blue – North of the Ecliptic.
Gray or dark blue – South of the Ecliptic.
The white line through the CM indicates the direction, but not the sense, of
its acceleration. The arrowhead on the green vector, also shown, supplies that sense.
As to that,
- the Sense of the Line of Position
- the Sense of the Line of Acceleration
- the
Distances between the bodies
- the Magnitude of the
Acceleration
all have no detectable relationship with the Phase Shift. |
