The Moons of Neptune

My 3rd grade daughter asked me to help prepare a report on Neptune.

I looked at wikipedia’s entry on Neptune, where it says Neptune has 13 moons.

I searched NASA for Neptune and it returned a list of links. I clicked on the first link listed and was directed me to a page saying Neptune has 11 moons. How was I going to explain this to my daughter? After a closer look I realized other pages at NASA agree with wikipedia.

This points out a deficiency in NASA: they can put a man on the moon but they can’t maintain a consistent database. Then I realized they are simply hosting World Book Encyclopedia‘s obsolete data. Hopefully new collaboration with Google will improve this situation. NASA uses a wiki for WorldWind , seems like they could wikify other areas too.

Speaking of NASA WorldWind, the Sloan Digital Sky survey is pretty cool, but I don’t see a way to search for planets/stars by name within WorldWind.
