Not only but also...

For the two bodies to remain perpetually opposite the Sun from each other, the orbits would have to be perfectly circular.

Not elliptical. In an ellipse, there are TWO foci, the Sun can only occupy one of them, so eventually (like for most of the year), the two bodies would be able to 'see' each other.

Planets travel in an ellipse, not a circle.


Yeah, that was all in my longer, accidentally-deleted version which included changes in eccentricity and apsidal precession.

Oh well. I see you & Phage got my back. Thanks.
