Created in 1994 by software developer and amateur astronomer Bill Arnett, The Nine Planets is a multimedia website containing information about our Solar System and beyond.

It was one of the first examples of a multimedia website when it first appeared online and has received over 100 million visitors. To this day, the site still receives up to 5 million visitors per year.
