Robert Schunk, I was reading some astronomy magazine with an interesting article about increasing discoveries of objects orbiting our Sun in the Kuiper Belt, and how these objects are all effected particularly by Neptune's gravity. Some folks are suggesting that it could be evidence to support an entirely new cosmology for planetary formation. New "discoveries" of Jupiter (and larger) sized "planets" orbiting much closer to their relative stars than where our gas giants also are a part of this. Current theories suggest planets formed at or near their current places, with the gas giants around the middle and the rocky Earth-sized planets nearer the sun. New theories suggest that possibly the gas giants can form nearer to their stars and then move out. How does Neptune play into this? If Neptune is a gas giant that formed nearer to our sun and then moved outward later its gravity could have attracted the 200 or so planetary sized objects in the Kuiper Belt. I thought this ridiculously interesting, it essentially flips the planetary formation model of the past 50 years on its head!
