Quite an accomplishment indeed. But how do we tell which pole is south? Penguins?
Right hand rule?
For large objects in the Solar System, the North pole is the pole that is to the North of the ecliptic (as determined by Earth's North pole). For small objects it is recently more common to use the right hand rule, and then one typically speaks of the "positive pole" and the "negative pole".
Missing polar bears!
Too hard to distinguish from missing pandas.
