Pluto is a planet. I grandfather it in. We can't demote it without better due process. And I object to scientists who think they have the right and the power to take words they didn't invent and alter their meaning. read more

Pluto’s [math]\Pi[/math] is [math]2.8times 10^{-2}[/math], so it’s only 2.8% of the mass it would need to be to be a planet. But if Pluto were at 1.7 AU, about the distance of Mars from the Sun, it would have [math]\Pi = 1[/math]. Eris could be at 2.1 AU and still be a planet. And the distance of planets from the Sun can change over time. read more

People think Pluto is still a planet because to those of us who hold to the geophysical definition, it IS one. Next time, you and the authors of this study should do their homework before citing one view in an ongoing debate as fact when that is far from the case, and doing so in an article replete with errors and misconceptions. read more
