I get 860 and 380, mass ratio 12.<br /><br />The only other comment I have is the overarching narrative. It&#39;s partly that while Orcus can be intermediate in size, albedo, density and size of satellite, the formation mechanism for Vanth surely can&#39;t be intermediate. Also that there seem to be three different stories blended together:<br /><br />1 - Orcus is another relatively important and interesting body so someone&#39;s got to do the measurements to get the shape of the jigsaw piece (here are the numbers);<br /><br />2 - Orcus is Malcolm in the Middle, let&#39;s see if that holds up (yes, it seems to);<br /><br />3 - Vanth&#39;s formation mechanism is obscure, can we determine it (not yet).<br /><br />Unfortunately I don&#39;t have any good suggestions to tidy it up.vagueofgodalminghttp://www.blogger.com/profile/09586713131483488218noreply@blogger.comtag:blogger.com,1999:blog-9094742788006644220.post-71269044223443664612009-12-21T10:00:50.562-08:002009-12-21T10:00:50.562-08:00Pavel --<br />Wow; that web site does an amazing job of taking real science and making it crazy. The discovery is a *supernova remnant* not a planet. And it is nowhere near us (though it is moderately close to being in the same *direction* as Pluto).

The key-theme of this object is &quot;to get involved&quot;, the hability to selfmotivate and motivate the teamwork enough to end the task at hands, like in the movie &quot;Snow White and the seven dwarfs&quot;.Amablenoreply@blogger.comtag:blogger.com,1999:blog-9094742788006644220.post-76724421969228224822009-12-03T13:28:34.806-08:002009-12-03T13:28:34.806-08:00I&#39;ve noticed that 2007 OR10 &#39;snow white&#39; now has a number (225088).

Is it good enough to locate the CoG of the system, and therefore discriminate a mass ratio of 2 from a mass ratio of 20?<br /><br />Also I&#39;ve noticed that 2007OR10 has recently be numbered.

And what 60Fe anomalies have yet been reproduced statistically different than zero in the same samples with the same sign?<br /><br />Jupiter ejects objects all the time. Why can&#39;t it get rocky matter out there? Why can&#39;t CAI&#39;s form out there from SNe/ nebular shock waves?
