Far off in the galaxy there is a star system with two planets. These two planets are unusual in that they have exactly the same orbit. They also both have the same rate of rotation. How can it be that one planet has a year that is 359 days long while the other has a year that is is 361 days long?

You can find the answer here.

One has the more interesting climate?

It is more interesting how many degrees they are apart in the same orbit.

I expected that the axis of rotation are in one case parallel to the plane of planetary movement and in the other case perpendicular to the axis of rotation...
