Sorry to resurrect a thread, but since this shows up on Google searches, you might want to note that you made the NASA error of forgetting to convert your units. The size listed for Europe is in square miles, not square km. Europe is just over 10 million km2, Australia 7.6 million. Still big, but not bigger than Europe. Or Brazil for that matter. While we're on it, Brazil is bigger than the contiguous US (i.e. minus Hawaii and Alaska.)
