Comments on: Mission to the Ninth Planet Second Largest (Known) Kuiper Belt Object http://blogs.discovermagazine.com/badastronomy/2006/01/16/mission-to-the-ninth-planet-second-largest-known-kuiper-belt-object/ I am an astronomer, writer, and skeptic. I likes reality the way it is, and I aims to keep it that way. My real name is Phil Plait, and I run the Bad Astronomy blog.

Where the issue lay is calling it a KBO instead of a planet. Its to me like calling the Earth an asteroid instead of a planet. I've kinda spelled out my stance on what makes a planet here: http://www.bautforum.com/showthread.php?t=37201 I'd be happy to continue there so we don't clog up Phil's blog with a major tangent. :) Oh, there I agree.

(Or put another way, why are the two categories mutually exclusive?) Why is Pluto being a KBO inconsistent with it being a planet?

Is there a <i>13:16 <b>a.m.</b></i>? And if so, is it tomorrow or yesterday? OK – not to nitpick (but that is sort of the etgos of this sight, isn’t it) -

Anyway, 13:16 p.m. Eastern time?

Is there a 13:16 a.m.? And if so, is it tomorrow or yesterday?

At what point is multiplicity applied? At what point is it logical? Multiplicity could be applied in that sense to strip Mercury, Venus, Earth and Mars of planetary status because they share the inner solar system with hundreds of other silicate bodies with distributed, layered interiors with some level of geological activity, they just happen to be the largest of them. What's to prevent the existance of Ceres and the other large, spherical asteroids with planet-like structural make ups from being a multiplicity factor that becomes a cornerstone for an arguement positing that the Solar System only has four true planets?
