Re: [Utah-astronomy] What's a planet?

Jim, IMO, this is a tempest in a teapot. No matter what the criteria are, someone will disagree. Too, there is no "Encyclopaedia Galactica" that spells it out as an Absolute Truth, so even criteria applied by the world's leading authorities is still thus, 'arbitrary'. If it looks like a duck, quacks like a duck, it's a duck. Pluto's a planet, Sedna's a planet. Big deal. --- Jim Gibson <jimgibson00@yahoo.com> wrote:

What criteria do you think should be considered in making such a judgment? Anyone else can answer for that matter.
