Reply to comment by [deleted] in Is it possible for two planets to orbit each other in a way where Planet A is tidally locked to the sun while Planet B is in geostationary orbit on the dark side of Planet A, thus putting Planet B in a constant total solar eclipse? by FenrirButAGoodBoy
Ehm, no, and you are right - having the same side to the sun always doesn't amount to nothing.
No, I was thinking more like two planets, close orbits, the outer slightly faster so it never really leaves the shadow of the inner. But I guess it is physically not possible to have a (two?) stable orbits of two big masses so close together that you'd see the shadow? I mean, even with the moon earth's shadow is so blurred the moon never gets black, just red.

The one further out would actually orbit slightly slower and fall behind.

As in that's a physical law? Or just we don't have examples to the contrary?

Physical law The further away you are the slower you rotate around the object.

Scratch that, just thought about it. Of course the dust disk where the planets come from would be slower on the outskirts and fastest at the center.

More like those funnel things that you can send coins down when you're at the museum.
