APPENDIX FOUR.
DEMONSTRATION:- The orbital periods (expressed in Earth days) of Earth, Venus, and Mars are (respectively) 365.25636 and 224.70067 and 686.9782
These periods can be verified by going to The Planetary Scientist’s Companion, by Lodders and Fegley, Oxford University Press 1998, Table 2.4
According to The Astronomical Almanac for 1981, page D2, The Lunar Node moves 0.05295383 degrees per day, which gives a value for The Lunar Node’s Revolution period of exactly 6798.375113 Earth days. This is calculated in the following manner:- The revolution period of The Lunar Node =
(360 ÷ 0.05295383) = 6798.375113 Earth days
During one lunar node revolution period, Earth revolves
(6798.375113 ÷ 365.256) = 18.6126 revolutions.
0.6126 x 360 = 220.5 degrees.
That is 18 complete revolutions + 220.5 degrees.
During one lunar node revolution period, Venus revolves
(6798.375113 ÷ 224.695) = 30.256 revolutions.
0.256 x 360 = 92.16 degrees.
That is 30 complete revolutions + 92.16 degrees.
During one lunar node revolution period, Mars revolves
(6798.375113 ÷ 686.980) = 9.896 revolutions.
0.896 x 360 = 322.6 degrees.
That is 9 complete revolutions + 322.6 degrees.
