it’s not clear to me that the observations you listed would be possible. … the only way I can make sense of your example would be to assume that the other planet is much heavier than yours
I don’t understand. The listed observations are in accordance with Newton, whatever the masses of the planets.
Yes, you’re right. It was my failure of imagination. I thought about it again, and yes, even with similar or identical masses, the rotations of individual planets around their own axes could be set so as to provide the described view.
