Enough to the point there were very noticeable continents, lakes, oceans, rivers and such on the inside if it.
The scales depicted here always bothered me. There is a curve to the sphere at the Jenolan's location that you just wouldn't see on something this size (radius of 1 A.U.)
Not to mention being able to see rivers and lakes at that distance. They'd have to be hundreds of thousands of miles across, at least.
I can at least visualize a continent or ocean which happens to be a million miles across, but I have a feeling when you get to that scale the rules of geography (not to mention geology) are totally different.
