Question

What is earth diameter

Answer 1

The average diameter of Earth is about 12,742 kilometers (7,918 miles). However, Earth is not a perfect sphere; it is an oblate spheroid, meaning it is slightly flattened at the poles and bulging at the equator. As a result, the diameter at the equator is approximately 12,756 kilometers (7,927 miles), while the diameter from pole to pole is about 12,714 kilometers (7,900 miles).
