Dear Friends,
Today I am extremely dissapointed that the Pluto Demoters have triumphed. I respect their opinion, but disagree with it. I strongly agree with Alan Stern's statement calling it "absurd" that only 424 astronomers were allowed to vote, out of some 10,000 professional astronomers around the globe. This tiny group is clearly not at all representative by mathematics alone. I believe we should formulate a plan to overturn this unjust decision and return Pluto to full planetary status, and as the first member of a third catagory of planets, Xena being number two. Thus a total of 10 Planets in our Solar System Please respond if you agree that Pluto should be restored as a planet. ken Ken Kremer Amateur Astronomers Association of Princeton Program Chairman |

What is the boundary on the ability of a planet to hold a hydrogen atmosphere? If I remember right, there's an exponential function of time in the equation, so the boundary should be fairly sharp. That seems like the most logical boundary between Terrestrial planets and Giant planets. Or is that already 10 MEarth?
As for "planetoid" meaning small, I know that was the historical meaning, but I think most people know that in general -oid just means "similar to." Lay people don't think "humanoids" are little humans, and I'm pretty sure scientists don't think spheroids are little spheres. :-) I think "planetoid" could work -- meaning that everything from Ceres to Jupiter would be a planetoid -- if the right people got behind it. That might just be you and Mike. :-) |

What would happen if we took Jupiter (as it is today) and put it in place of Mars? Would Jupiters strong gravity and magnetosphere help protect Jupiter from the now stronger solar winds and radiation? Or would Jupiter be reduced to a 10 Earth Mass object in 1 billion years as it is stripped of most of it's hydrogen and helium?
