This is how it looks after import rotated in Mathematica:

o = Import["http://sci.esa.int/science-e/www/object/doc.cfm?fobjectid=54726", "OBJ"];
Show[o, SphericalRegion -> True, Background -> Black]

I suspect that there is minimal data on the “flat” opposite side and so it has a digitally smoothes surface.

Another way to get the object is via a MeshRegion:

o = Import["http://sci.esa.int/science-e/www/object/doc.cfm?fobjectid=54726"];    
MeshRegion[Cases[o, {"v", __}][[All, 2 ;; 4]], Polygon[Cases[o, {"f", __}][[All, 2 ;; 4]]]]

And here is the Rosetta spacecraft taking a selfie at 472 million kilometers from planet Earth and only 16 kilometers from the surface of comet 67P/Churyumov-Gerasimenko. Check out what 472 million kilometers is. This is the source - quoting:

This Rosetta spacecraft selfie was snapped on October 7th. At the time
the spacecraft was about 472 million kilometers from planet Earth, but
only 16 kilometers from the surface of comet
67P/Churyumov-Gerasimenko. Looming beyond the spacecraft near the top
of the frame, dust and gas stream away from the comet’s curious
double-lobed nucleus and bright sunlight glints off one of Rosetta’s
14 meter long solar arrays. In fact, two exposures, one short and one
long, were combined to record the dramatic high contrast scene using
the CIVA camera system on Rosetta’s still-attached Philae lander. Its
chosen primary landing site is visible on the smaller lobe of the
nucleus. This is the last image anticipated from Philae’s cameras
before the lander separates from Rosetta on November 12. Shortly after
separation Philae will take another image looking back toward the
orbiter, and begin its descent to the nucleus of the comet.
