Main Question or Discussion Point

The graph I have made of Average Orbital Distance from the Sun vs. Average Orbital Velocity illustrates a decreasing exponential function. How, if it does, would this suggest that there is dark matter present in our solar system?

Dark matter in our solar system is estimated to have a total mass equivalent to a small asteroid, so it's affect on orbits is negligible to a large number of decimal places. If you are getting other results, I would suggest reworking something.
