-Mercury moves during its day period (175.94 solar days) a distance (720.7 mkm)= = Mercury Jupiter Distance -Venus moves during its orbital period (224.7 solar days) a distance (670 mkm) = = Venus Jupiter Distance (error 1.5%) -Earth moves during its orbital period (365.25 solar days) a distance = Earth Jupiter Distance (when Earth & Jupiter be at different sides from the sun 778.6 mkm +149.6 mkm = 929 mkm) (error 1%) Why do The 3 Planets Move During Their Orbital Periods (Or Day Period) Distances = Their Distances To The Jupiter?! My Answer Which I Try To Prove In This Paper. -There's A Light Beam Its Velocity =1.16 Mkm/Sec -This light beam (1.16 mkm/sec) creates the orbital and internal distances between all solar planets and Specially between (Jupiter, Mercury, Venus & Earth) -The inner 3 planets (Mercury – Venus – Earth) are followers to Jupiter and they consist together one unified motion – that means- they are 3 carriages in one train and they move complementary motions to each other -Jupiter is the guide and head of the 3 inner planets (Mercury, Venus & Earth) – Jupiter works as a reference for them (Specifically, Jupiter is the source of energy for these 3 inner planets). Jupiter & The 3 Planets Data Prove, There's A Light Velocity =1.16mkm/Sec Gerges Francis Tawdrous +201022532292
