Have we observed objects orbiting around the sun in the 'wrong direction'?

I know that the solar system originated from a spinning disk of gas and debris, and as such, all of the planets orbit in the same direction as the sun's own rotation, and with a bit of reading, it appears that the same is true for comets and asteroids.

I also have read about moons in the solar system that didn't originate from the same material as their companion planet, but were instead captured as they zipped past, and as such they orbit 'backwards'.

Have we observed asteroids or comets that are orbiting the sun backwards in relation to all of the planets? If so, or if we do in the future, can we then safely presume that the object originated outside our own solar system?

None of the big stuff, but, famously, Triton is retrograde around Neptune.  Also, Venus rotates backwards, and Uranus rotates at an almost 90 degree angle, both of which are extremely large deviations from the basic angular momentum story.  So, as you suggest, that at least tells us that something pretty crazy and pretty big happened to them at some point.
