Where is earths circumference greatest

Whatever angle it creates on one parallel line, it creates the same angle on the other. If he could accurately measure the stick's shadow angle in Alexandria at local noon on the summer solstice, Eratosthenes have both pieces of information needed to calculate earth's circumference.

Eratosthenes did the measurement and found the angle was 7. That angle, 7. So, if km or mi. The earth, as we said, is an oblate spheroid, so geodesists scientists who measure the earth and its position in space have measured and calculated the average of earth's circumference as 40, km or 24, mi. Eratosthenes, some 2, years ago, was off by only km or mi. And he did it with just a little knowledge about geography and mathematics, a well, and a stick. Inscribed Angle.

Related: What's the speed of Earth around the sun? Earth's density is 5. Earth is the densest planet in the solar system because of its metallic core and rocky mantle.

Jupiter, which is more massive than Earth, is less dense because it is made primarily of gases, such as hydrogen. Earth's mass is 6. Its volume is about billion cubic miles 1 trillion cubic kilometers. The total surface area of Earth is about million square miles million square km. For comparison, the total surface area of Venus is roughly million square miles million square km , and that of Mars is about 56 million square miles million square km.

Mount Everest is the highest place on Earth above sea level, at 29, feet 8, meters , but it is not the highest point on Earth — that is, the place most distant from the center of the Earth. Although Chimaborazo is about 10, feet 3, m shorter relative to sea level than Everest, this mountain is about 6, feet 2, m farther into space because of the equatorial bulge.

The circumference of the Moon is 10, km, and the circumference of Jupiter is , km. Here are a bunch of measurements for you: Circumference of the Earth in kilometers: 40, km Circumference of the Earth in meters: 40,, meters Circumference of the Earth in centimeters: 4,,, centimeters.

Circumference of the Earth in miles: 24, miles Circumference of the Earth in feet: ,, feet Circumference of the Earth in inches: 1,,, inches. We have written many articles about Earth for Universe Today. Here are some photos of the Earth and Moon together , and here are the 10 most impressive impact craters on Earth.
