The Earth has:-

  • Polar Radius: 6,356.8 km (3,950 miles)
  • Equatorial Radius: 6,378.1 km (3,963 miles)
  • Mean Radius: 6,371 km (3,958.75 miles)
  • Mean diameter: 12,742 km (7,917.5 miles)
  • Equatorial circumference: 40,075.02 km (24,901.24 miles)
  • Surface area: 510,072,000 km2 (196,939,900 miles)
  • Volume: 1.0832073 × 1012 km3
  • Mass: 5.9736 × 1024 kg

The diameter of the earth at the equator is 7,926.41 miles (12,756.32 kilometers).
the earth is 24,901 miles and 39,842
The mean radius of Earth is 3,959 miles (6,371 kilometers). However, Earth is not quite a sphere. The planet's rotation causes it to bulge at the equator. Earth's equatorial diameter is 7,926 miles (12,756 kilometers), but from pole to pole, the diameter is 7,900 miles (12,720 km) - a difference of only 40 miles (64 km).
The size of the Earth is measure in parameters generally, and it is estimated and believed to be measured at around over 40,000km in circumference, and over 500 million km squared in terms of surface area. Its radius is ca. 6350 km.
