Also the second largest impact structure on Earth, the 1.85 billion years old Sudbury crater in Canada, hosts world-class mineral deposits - in this case nickel-rich minerals that were melted and concentrated by the extreme heating caused by the impact.
The circumference of Earth at the equator is about 24,902 miles (40,075 km), but from pole-to-pole â the meridional circumference â Earth is only 24,860 miles (40,008 km) around. This shape, caused by the flattening at the poles, is called an oblate spheroid.
Here you will find a listing of essential facts about planet Earth, the home to all of humanity: The circumference of the Earth at the equator is 24,901.55 miles (40,075.16 kilometers), but, if you measure the earth through the poles the circumference is a bit shorter, 24,859.82 miles (40,008 km). The shape of the Earth: The earth is a bit wider than it is tall, giving it a slight bulge at the equator.
