Is the planet rotating ? If so, how are the orbits aligned wrt to the poles ?

Assuming the planet is in inertial frame, equal times elapse on the ships between meetings.

Doesn't special relativity predict time dilation between the two ships since there is a relative velocity between them?

They may see each others clocks running differently, but the ageing, or elapsed time will be the same for both when they meet.

What do they see?
