I think the point is "planet X" tends to be a generic term for a body(or bodies) that may exist based on observation or probability, and also used (because it sounds so cool) as the name for some "alien planet/planet-craft" that roams the galaxy building pryamids and moon-faces. One is an astronomy discussion and the other is...to be polite...a CT. (also better words to describe it but I'll stay within BAUT rules
)
Only downfall to all this is I'll haveta go back to daily comic-strips to get my daily dose of humor, as now that the non (outer)space/science CT's are locked, CT-section activity is drastically lower
