Yes, there is one from a while ago in Solar System Anomalies forum. This is where we have put the asteroid fly-by posts in the past, but I am sure it does not really matter that you have posted another. The mods can either move it or merge it with the other which is here Asteroid Vesta
The attached are: 1, of Vesta. 2, a ' crater '( arrow marked on 1 ). And while I cannot seem to locate a previous post on Vesta ( can anyone help here?), am including a pic from that set ( ' 3 ' ) of a Triangular City located there. Vesta, I surmised, originally had a cyrstal tetrahedron shape, now badly damaged, its original shape however is still readily visible. I am therefore of the opinion that this ( Vesta ) was constructed, and is but another piece ( or pieces now ) in the legendary " war in the heavens ". That it was a great warship, perhaps a flagship, in an ancient forgotten war, and what we see in the submitted photo (2), is actually the exposed " innards " of this great ship. These are the levels, and machinery, once part of the Warship, and its ( now ) scrambled pieces being the remains of the powerplants, machinery, and quarters, left from a devestating hit ( the 'crater ' )that it took in that titanic war. There is much further evidence for this reconstruction of what we are actually dealing with in Vesta, but suffice for now, there is indeed much to seriously ponder and consider here.
