Earth radius (denoted as R🜨 or RE) is the distance from the center of Earth to a point on or near its surface.
Earth’s orbit around the Sun is not circular, but an ellipse. The perimeter of Earth’s orbit is roughly 584 million miles (940 million km).
Earth is not a perfect sphere. In fact, it’s in the shape of an oblate spheroid. Earth shape bulges at the equator and flattens at the north and south pole.
What are the semi-circles on a globe? While latitudes are full circles that traverse around the globe, longitudes are semi-circles that run from one pole to the other.

the earth is a semi-circle. we are living on the flat part of the semi-circle and the rounded part would be full of more layers of the earth, or other known as parallel universes. this could be because the earth was once round but was sucked into a black hole and shot out of a white hole, but was ripped in half, which could explain ...
Each great circle is divided by the poles into two semi-circles called meridians of longitude. As the meridians run north and south, places having the same longitude will be due or due south of each other.
Columbus's error 1,700 years after Eratosthenes's death, Christopher Columbus studied what Eratosthenes had written about the size of the Earth. Nevertheless, based on a map by Toscanelli, he chose to believe that the Earth's circumference was 25% smaller.
