While playing with online NASA Solar simulator V4:
http://space.jpl.nasa.gov/index.html
I found a minor defect. When you try to see Saturn from the sun, the Suturn's rings sometimes are black instead of constant bright. This seems not happen with a specific time window, but with the order you change the date. But I could not figure out what pattern of date change will trigger this bug into action.
I did not see this problem happen when try to see Saturn from Mercury or Venus.
Please look at the screenshot, one ring is dark and the other is bright.
The problem has been reported to the NASA developer already.
