Earth - Third planet from the Sun, first in our hearts. The Earth has an equatorial radius of 6378 km (3963 miles) and a polar radius of 6,357 km (3950 miles). So no matter where you are on Earth, the farthest thing from you is only a short 20,037 km (12,450 miles) trip away. At least until we start building mega tunnels.
