comment How did the Mars satellites “take cover” from the recent comet flyby?
My question wasn't how to gauge whether the encounter with comet would affect instrument quality, but whether changing the orbit itself will affect the spacecrafts' ability to fulfil their primary missions in relation to Mars.

comment What is the difference between a dwarf spheroidal galaxy and a globular cluster?
This is incorrect. There are many so-called "satellite" galaxies that orbit the Milky Way without orbiting the Local Group's center. Check out this Wikipedia article for a list: en.wikipedia.org/wiki/List_of_Milky_Way%27s_satellite_galaxies

I wasn't looking at a rotating frame, but your comment is valid for a rotating frame.
