Many of the statistics and other info was obviously not done by us. This is mainly because we'd need billions of dollars and sophisticated devices to help us come up with accurate measurements and other stats! Being that as it is, we sought out to find a non-profit organization with the manpower and brainpower to help us out. This inevitably led us to the National Aeronautics and Space Administration (a.k.a. NASA)! With there online facilities we obtained very accurate measurements and facts that helped us bring you our great site! We also got some info from other sources, so now we take the time to thank and acknowledge them for their resources...
