Technically, there really isn't a definition for the word "Planet", atleast not in science. Planets can be described easily in dictionaries, but scientists question the definition. They don't have a real answer to what planets are and how to describe them, but that's why scientists are searching and discovering things about planet to have a REAL, CLEAN, and SCIENTIFIC definition for the term, Planet.
