I just removed the exoplanets tag from this question, which clearly just needed the planets tag. The exoplanets tag is still used on this question, which involves arriving in another planetary system, viewing the planets as exoplanets, as opposed to planets in viewer's original system.
I'm in favor of this, because I can't see many questions needing to differentiate between planets and exoplanets.
Besides, exoplanets are just planets that aren't near where you are. It's similar to the idea that ever person is a foreigner - to someone else.
