Oof. I am becoming skeptical that a hand-drawn illustration will capture the details - I would have to intuit what dimensions can be...

OK, I am hoping that you will intuit that, for a given speed, a shorter time spent in retrograde would result in a smaller observed...

Yes, you did mention that. Altough surely the magnitude is affected by the relative velocities because they affect when, in their...

Are you accounting for Earth's peri/aphelion at the times of opposition? (green arrows in diagram) For example, if Earth happens to be...

Well now I want an app that will tell me what category I fall into, just by saying yea or nay to a list of music. I have always...
