Is it a planet, or not?

<!--EZCODE LINK START--><a href="http://www.spacedaily.com/news/outerpla ... l">Gravity Rules</a><!--EZCODE LINK END--><br><br>An interesting proposal to define the lower end of what constitutes a "planet," since there's been so much controversy about that of late. Pluto, Sedna, etc. It's nice because it bases the definition on physical principles as opposed to someone throwing a dart at a chart and arbitrarily saying "bigger than this is a planet." <p></p><i></i>
