halacha - When and how often would someone say Kiddush Levana (Blessing for the moon) if he were on another planet?


This M.Y. answer says that there are differing views as to whether someone is exempt from mitzvoth while in space.


If we were to follow the opinion that one is obligated, should a person on Jupiter be saying Kiddush Levana for each of its 62 known moons ? What if more than one moon is visible?



Or, is Kiddush Levana only done regarding Earth's moon? Does it need to be visible to the naked eye, or what if one on Jupiter viewed Earth's moon in a telescope or it just appears as a "star"?


My question would apply to any planet that had multiple moons.
