Eris has weather!
space.com article about seasonal atmospheric ices transfer on Eris: http://www.space.com/scienceastronomy/0811...arf-planet.html Nitrogen sublimates first, then deposits first on the colder pole. Methane sublimates next, then deposits on top of nitrogen on the colder pole. If I understand this correctly, the layering would be unstable, with the more volatile (nitrogen woofs off at a lower temperature) component buried under the methane layer. Could make some really impressive nitrogen jets through the methane ice surface during the spring "warm up". -Mike -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/
