Lost in Space

The Earth seems so large to us, even with modern technology. How long is a flight to Japan, close to 24 hours? How many people have been shipwrecked in the Atlantic or Pacific Ocean and never see anyone again, floating for weeks in the seemingly endless expanse of water. How big is the Grand Cayon? It is 217 miles long, varies in width form 4 to 18 miles and it's 1 mile deep, deep enough to put the worlds tallest skyscraper inside.

But the size of the Earth pales in comparison to many other heavenly bodies out there in deep space. Take a look at The Size of Our World.
