The Earth and the Moon, with sizes and distances to scale. (click for image)
|
Outer space is a big, empty place. The Earth's nearest neighbor, the Moon, is still an enormous 238,855 miles (384,401 Km) away. For comparison, you would have to circle the globe roughly 10 times to travel that distance. Assuming that you won a non-stop flight to the Moon on Boeing 747 plane, which flies at roughly 600 miles (1000 Km) per hour, it would take you more than two weeks to get there!
