A tip on speed of light units
A major advantage of Physics in terms of speed-of-light unit is we do NOT have to deal with huge numbers if we are to make a down to the pen and paper calculation. This is possible because speed of light is a constant even though a large number. So you can compute everything as if…

Moving clocks run faster in the Doppler hemisphere of approach
Moving clocks run faster in the Doppler hemisphere of approach, run slower in the Doppler hemisphere of recession and run slower in the Doppler plane of intersection of hemisphere of approach and recession. The GPS satelites eg are in constant free fall towards earth and located in the Doppler plane of intersection, they never approach…

a simple calculation for earth spin projected onto sun-earth orbit plane.
Here is the earth-around-sun and earth-spin situation: Earth rotates around sun in a tilt of 23.5 degrees and earth rotates around itself with spin S. SO S is 84% along sun’s vertical and 16% along sun’s horizontal;
