Re: [meteorite-list] Solar System in Perspective
I think EL 61 rotates fairly rapidly and it is thought that this shape was frozen in when it was formed. This is where the actual defining of a planet gets a little fuzzy and where I start having problems with, if not the definition, how do you determine what is and what is not a planet. The definition is not perfect, but this and how it is implemented are things that can be worked out.

Re: [meteorite-list] Solar System in Perspective
Hi, Pete, I second those thanks! These are new pages for the IAU site. They weren't there in the wee morning hours before last when I was trying to find a mention of Proposal V on the website -- there weren't NONE! About 2003EL61, Darren. Despite the iceball myth about KBO's, 2003EL61 is SOLID ROCK. The density is way too high to be anything else. It doesn't even seem to have any superficial surface volatiles. It don't snow on Santa. Isn't that a CW song? But with a four hour rotation, er, axial revolution, period, this massive object is far from round. I haven't (can't) calculate the degree of strain in the body of the planet, but it must stupendous! Big question is: is it frozen in and dating from its formation, or is it a dynamic distortion. I don't know the shear modulus, or modulus of rigidity, of 2003EL61 or any planet, and I doubt that anybody does... Santa is in the Wikipedia: http://en.wikipedia.org/wiki/2003_EL61 Here's a big image, er, artist's conception: http://en.wikipedia.org/wiki/Image:2003EL61art.jpg In fact, the Wikipedia has very good entries on all the KBO crowd...
