In this first, hybrid type, theory, the Earth’s perihelion precession is calculated from the general Lorentz transform by assuming that its velocity is cap omega x r where cap omega is the gravitomagnetic field. The method gives the observed precession of 11.45 arcseconds a year with a velocity for the Lorentz transform of 6.7685 ten power five metres per second. In the non relativistic theory where there is no precession, the orbital velocity of the earth about the sun is about 3 x 10 power four metres per second, or thirty kilometres per second. A more accurate method is to use a lagrangian analysis to derive the generally relativistic Binet equation. That will be the subject of the next note.
