1. Great pictorial presentation.
Do you have a link where I can view it in a larger size, so I can read the captions?

2. I would love to see this normalized...
...to remove the Sun's gravity. It strikes me as very odd to see Mercury's well nearly as deep as Jupiter's.

It's a great presentation as is, though.

6. That may be the reason Mercury is shown so far down: its proximity to the Sun...?

9. Yeah. The depth of the pictured wells shows not merely escape velocity...
...from the bodies in question, but also the energy needed to escape from the Sun (at the range of the body's orbit) as well.

5. Pluto was bad and had its planethood removed.
