This is a great image caught by amature astronomers that I found on UniverseToday.com. It is still undetermined what the orbit and exact nature of the object is. It's possible that it is a man-made object, perhaps a spent rocket booster from the ESA's Venus Express. Check out UniverseToday.com for more images and more information. It's a great site!
UPDATE:
This was supposed to be an animated .GIF, but I haven't figured out how to get Blogger to display them properly. The asteroid is the small white dot at the center of the image. Hopefully I'll get the image fixed soon.
