Is this about right? I can find Today, we measure the earth.

Eratosthenes, some 2,200 years ago, was off by only 125 km or 101 mi. Eratosthenes made a calculation by multiplying the distance by the angle. He was able to determine the Earth's circumference and then another calculation to work out the diameter. Today, I’d like to tell you a story of one of these methods that dates back more than 2,200 years. It’s the story of a brilliant Greek astronomer and mathematician named Eratosthenes and his efforts to measure the size of the Earth.

2014-06-12 · The Earth has a liquid core and a solid crust which is broken into several plates which slowly move along the surface of the planet. The surface is covered approximately 70% by liquid water. The mass of the Earth is approximately 6.5 x 10^21 tons (5.98 x 10^24 kg) and the mean diameter of the Earth is 7,926 miles (12,753 km).

This means that the Earth is rushing through space around the sun at a rate of about 29,000 m/s (66,000 mph)! However, Earth does have a diameter to measure.

And Earth is the third-closest planet to the sun. Its average distance from the sun is about 93 million miles. The Earth viewed from moon will appear larger, in proportion to how much larger the Earth's diameter is versus the moons diameter. Earth diameter 7900mi; Moon diameter 2100mi; So the Earth-view from the moon would appear 3.75 times as large as the Moon appears in the sky on earth.

Earth's circumference (the distance all the way around the equator) is 24,901 miles (40,075 kilometers).

Our planet is pudgier at the equator than Real Diameter.

Measurement of Earth's circumference has been important to navigation since ancient times. Earth has a diameter of roughly 8,000 miles (13,000 kilometers) and is round because gravity pulls matter into a ball. But, it's not perfectly round. Earth is really an "oblate spheroid," because The Earth is about 40 thousand kilometers (about 24,860 miles) around. The measurement that Eratosthenes made might have been within about 1% of this. That would be amazing!
