Bob the Alien's Tour of the Solar System is split into sections dedicated to each of the main celestial objects. It also looks into the history of astronomy and space exploration. Also included are useful resources such as a table of all the planets and dwarf planets, an A-Z glossary of space terms, a timeline of space exploration and a section where visitors can ask Bob the Alien a question about space.
Although initially designed for the younger astronomer and astronauts of the future, the site has grown in size and scope over the years that it's been taking up space on the Internet, and is ideal for anybody with an interest in its subject matter. Each month, up to 50,000 visitors from all over Earth join Bob the Alien and Bobsdog on their inter-planetary voyage of discovery.
