Radius, diameter and circumference The radius of Earth at the equator is 3,963 miles (6,378 kilometers), according to NASA’s Goddard Space Flight. Because of this, the diameter of the Earth at the equator is about 43 kilometers (27 mi) larger than the pole-to-pole diameter. As a result, the. The diameter of the Earth at the equator is 12,756 kilometers (km). How Do We Calculate Distances of This Magnitude? Clementine image of Earth -. Earth’s circumference (the distance all the way around the equator) is 24,901 miles (40,075 kilometers). Its diameter (the distance from one side to the. The diameter of Earth can be measured from the North Pole to the South Pole, or it can be measured at the equator. There is a difference of about 43.

## Circumference of Earth

As it turns out, the meridional circumference of Earth (from pole to pole) is roughly 40,008 km, and the equatorial circumference is about. In the third century BCE , Eratosthenes, a Greek librarian in Alexandria , Egypt , determined the earth’s circumference to be 40,250 to 45,900 kilometers (. This means that Eratosthenes estimated the circumference of the Earth to be about 40,000 km. He also knew that the circumference of a circle. If you like, you can calculate the Earth’s circumference yourself. The formula for calculating the circumference of a sphere is 2 x pi x radius.C Kafal? · 2018 Eratosthenes sent a man to Syene from Alexandria on foot to measure the distance between Alexandria and Syene. Thus, Eratosthenes measured the distance between.

## Diameter of earth in miles

For modern definitions and measurements, see Earth radius. Earth’s circumference is the distance around Earth. Measured around the Equator, it is 40,075.017 km. This is worked out by adding Earth’s polar and equatorial diameters and then dividing this number in half. This gives us a mean diameter of 12,742 km or 7917.5. Distance Information. The diameter of the Earth at the equator is 12,756 kilometers (km). How Do We Calculate Distances of This Magnitude?Measured at the equator, the circumference of the Earth is 24,901.55 miles. However, the Earth is not quite a perfect circle, and if you. The radius of the earth is about 6000 kilometres, which is 6 million metres or 6 hundred million centimetres. Let’s write that as centimetres. So its volume is.

## Moon size

Moon, Earth’s sole natural satellite and nearest large celestial body. Because of the Moon’s small size and mass, its surface gravity is. Even though we can see the Moon shining brightly in the night sky and sometimes in daylight it’s hard to put into perspective just how. This illustrates the relative sizes of Uranus, Earth and Earth’s Moon. The images are shown at the proper relative size, but not the correct relative. The sun and the moon are about the same size when you look at them in the sky, though that’s just thanks to the coincidence that the sun is about 400 times. But the difference is small, just four kilometres. The equatorial diameter of the Moon is about 3,476km, while the polar diameter is 3,472km. To.

## Moon diameter

The equatorial diameter of the Moon is about 3476km, while the polar diameter is 3472km.This illustrates the relative sizes of Uranus, Earth and Earth’s Moon. The images are shown at the proper relative size, but not the correct relative. The Greeks already knew the diameter of the Earth, about 13,000 km and so they could then calculate the Moon’s diameter (3700 km). As the Moon is 110 Moon. Because it’s rotating, the Moon slightly flattens out. I say slightly, because we’re going to need decimals to really tell the difference. The. “The Moon’s diameter is 2,159 mi (3,475 km) and its circumference is 6,790 mi (10,864 km).The moon is 27% the size of the earth.” 3.48 × 106 m. As the only.
