Explanation / Answer

Astronomers used to say that mars wondered since itdidn't do what other stars did, it would wonder from constellationto constellation. You can compare this behaviour with our moon, itwill seem to be on top of one constellation at one time and acomplitelly different at another. This movement is obviously not asnotizable for planets since they are much further away and orbitingaround the sun not us of course. Anyways The answer is a) A very slow movement with respect tothe background stars, barely noticeable from night to night.
