 Steven Soter prefers to use the term "dynamical dominance" and Jean-Luc Margot notes that such language "seems less prone to misinterpretation".Prior to 2006, the IAU had no specific rules for naming planets, as no new planets had been discovered for decades, whereas there were well-established rules for naming an abundance of newly discovered small bodies such as asteroids or comets.The naming process for Eris stalled after the announcement of its discovery in 2005, because its size was comparable to that of Pluto.
