That's Mercury, and you're correct on all counts as to why it's Mercury or Venus.  I can tell you it's Mercury because of it's apparent magnitude, and also because the instrument the video comes from doesn't have the field of view to see the entirety of Venus's orbit.

Just to back you up further! :) This is the view from the SECCHI viewer  for the date in question (it's an attachment so you need to be logged in to see it).

Thanks jules!!!  ;D

I think I read somewhere that the field of vision of stereo is roughly about 20 degrees? So i would assume Venus is just right out of its field of vision?

Oh btw, if i use the SECCHI viewer, it doesn't matter which comet orbit i choose since the planets orbit will be the same right?

Yup!  Actually, Venus just out of frame is causing the arc/ring on the right side of the image.  Internal reflections on the optics, aka lens flares.

Correct that it doesn't matter which comet orbit you choose on the viewer.  We're not using it for it's intended purpose.   ;D

It's amazing how much information you can get out of just one image isn't it?  ;D 8)
