How rude not to show the picture...
Some Sedna images.
By means of explination. The bottom left was the parallax image I described in my last post, showing a streaking Sedna next to an apparently motionless star. This was a 16 hour exposure, so all of the motion of Sedna that you see is from the parallax, and not from the orbit of Sedna itself.
Top image is the orbit of Sedna, as seen from earth. It seems to spiral because of the motion of the earth around the sun, not because it has some funky orbit. It's still going around in an elipse, but the orbit of the earth creates what is known as a retrograde.
Bottom right is Sedna in all its pixelated glory.
