Retrograde motion of the planets is described here.The observed angular diameter change fits with the heliocentric model. What is the flat earth explanation?
I still don't see what the angular size change of a body above us has to do with the shape of the earth.
The explanation is that the observed angular change fits with the flat earth model.
How does an observed angular diameter change of 5x fit with model? Please explain.
If you can tell me orbital period and orbital diameter of Venus around the sun, I'll plot it out and see if it fits. Maybe you've already done this since you say it works.
Secondly, you must not ascribe to the firmament model. For Venus to have a large enough orbit to be out of the light of the sun its orbit would have to go outside of the dome.....or the dome would have to be quite a bit larger than the flat earth map.
