WebbThe radius of the Earth depends on how you define it. The distance from the center of the Earth to the point on the solid surface of the Earth furthest from the center is 6,384,415.98 meters (20,946,246 feet and 8 inches). That point furthest from the center is the summit of Mt Chimbarazo in Ecuador. WebbA typical extrasolar "hot Jupiter", HD 209458 b, has a Hill sphere radius of 593,000 km, about eight times its physical radius of approx 71,000 km. Even the smallest close-in extrasolar planet, CoRoT-7b , [6] still has a Hill sphere radius (61,000 km), six times its physical radius (approx 10,000 km).
