That is amazing! <div class="Discussion_UserSignature"> Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars Arthur Clarke </div>

Replying to: <DIV CLASS='Discussion_PostQuote'>That is amazing! Posted by jonclarke</DIV> Orbital elements here. Yes I agree completely Jon, it is an amazingly wierd looking object.To me looks like a fragment, a real knarled up piece of rock. Perhaps a probe will get to see it up close one day. It is a little larger than 25143 Itokawa that Hayabusa has shown us so spectacularly. The orbital around the Sun is 2.47 years. Perihelion: 0.5965 AU. Aphelion: 2.0496 AU. Orbital Inclination. 5.89 degrees. Earth MOID (Minimum Orbit Intersection Distance): 0.000792756 AU.

Posted by 3488</DIV> Actually it looks very much like a paleolithic stone scraper tool.  These were first invented about 2M years ago by H. Erectus and used for skinning and flesh removal from kills.Of course this asteroid isn't a giant sized prehistoric scraper, but it may have been formed in a similar manner.  If a stone is struck in just the right places, it will flake off portions to leave a triangular core with at least one sharp edge.  Conceivably this could have happened by collisions.Below is a stone scraper from Kowanyama Land, Australia <img src="http://sitelife.space.com/ver1.0/Content/images/store/6/11/26dc4b8a-21e0-4461-bb14-2b11f6608eea.Medium.jpg" alt="" /> <div class="Discussion_UserSignature"> <div class="Discussion_UserSignature" align="center">- - - - - - - - - - - - - - - - - - - - - - </div><div class="Discussion_UserSignature" align="center">I really, really, really miss the "first unread post" function. </div> </div>

Maybe it's a rubble pile, like Hayabusa, but with three main lobes instead of two. <img src="http://sitelife.space.com/ver1.0/Content/images/store/7/12/67f8472e-3952-452d-8c47-6bf6a834bf80.Medium.jpg" alt="" /> <div class="Discussion_UserSignature"> </div>
