Very nice. I'd like to make a couple of upgrade suggestions if they are doable. They might be difficult to pull off.

First, when clicking on an individual planet or moon link, could it go to a far more detailed view of that planet or moon? Essentially a Google earth type view of every planet or moon in as much detail as we currently know?

Second, having another link that shows all exoplanets in relation to their stars, and individual links to exoplanets in their stars' habitable zones? Also, maybe a text box with information about what we currently know about the exoplanet?

This feature could draw in people doing online searches for exoplanet information, and it would be consistent with the name of this website.
