>>Nice picture.

>>For your information, it seems, so far, that the real Sedna doesn't have a moon.

>That image is the same one I have been using for the background wallpaper for my slide decks in presentations lately, see the PPT deck at http://blogs.msdn.com/klevy/archive/2005/10/25/484955.aspx. But I don't think it is an actual photo, but instead a graphical artist rendering of what it might look like up close based on data they have on the object out there.

Indeed, it is quite obvious that the image is an artist's representation. First, the style, which looks more like a drawing (well, so do photographs of some of Jupiter's moons, for that matter...). Also, about all we can get from an object that far off, for now, is the light intensity and perhaps the color, not that much details.
