Circumference of the Earth The circumference of the Earth in kilometers is 40,075 km, and the circumference of the Earth in miles is 24,901. In other words, if you could drive your car around the equator of the Earth (yes, even over the oceans), you’d put on an extra 40,075 km on the odometer.

- In the third century. , Eratosthenes, a Greek librarian in. , determined the earth's circumference to be 40,250 to 45,900 kilometers (25,000 to 28,500 miles) by comparing the Sun's relative position at two different locations on the earth's surface.

How Many Miles Around the Earth? Planet Earth, which we humans and all currently-known forms of life call home, is the third planet from the Sun, and the largest of the terrestrial planets. With a mean radius of 6,371 km (3,958.8 miles), it is slightly larger than Venus (which has a radius of approx. 6,050 km), almost twice the size of Mars (~3,390 km), and almost three times the size of Mercury (~2,440 km). Basically, Earth is a pretty big world.

Earth Surface Area of the Earth. by Jerry Coffey on February 18, 2009. The surface area of the Earth is 510 million square kilometers or 5.1×10 8 km 2. The Earth is a water heavy planet, so, if you break its surface area into water and land segments, it would look like this: land 149 million km 2, water 361 million km 2.

How large is 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 other through Earth's center) is 7,926 miles (about 12,756 kilometers).Earth is slightly smaller when measured between the North and South Poles which gives a diameter of 7,907 miles (12,725 kilometers).Earth bulges out a bit more around the equator than around the poles because of its rotation (spin). 1  Javascript must be enabled to use Cool Cosmos. 2  Learn how.arth is slightly smaller when measured between the North and South Poles which gives a diameter of 7,907 miles (12,725 kilometers).

- The circumference of the earth at the equator is almost exactly 24,900 miles. It takes 24 hours for the earth to rotate on it axis so the earth is rotating at a little over 1, … 000 miles an hour (1037.5 miles per hour to be a bit more exact). Answered.

- As a consequence, a line of longitude wrapped around the  Earth going through the north and south poles is about 24,859.73  miles, or 40,007.86 km long. That makes the Earth's circumference  about 42 miles longer (about 67 km longer) measured around its  middle than around its poles.

- A stadion in ancient Greece was thought to be the equivalent of 600 feet today, so 250,000 stadia was 150 million feet. That was Eratosthenes' estimate of Earth's circumference. The real distance is 24,859 miles, or 131,259,849 feet.

What is the diameter of Earth? But, if you measure the earth through the poles the diameter is a bit shorter - 7,901 miles (12,715.43 km). Thus the earth is a tad wider (25 miles / 41 km) than it is tall, giving it a slight bulge at the equator. This shape is known as an ellipsoid or more properly, geoid (earth-like).

How Big Is Earth? The planet's rotation causes it to bulge at the equator. Earth's equatorial diameter is 7,926 miles (12,756 kilometers), but from pole to pole, the diameter is 7,900 miles (12,720 km) — a difference of only 40 miles (64 km).arth is the densest planet in the solar system because of its metallic core and rocky mantle. Jupiter, which is 318 more massive than Earth, is less dense because it is made of gases, such as hydrogen.

Geodesy and the Size and Shape of the Planet Earth Earth is classified as the largest of the terrestrial planets based on its circumference and diameter as well. At the equator, Earth's circumference is 24,901.55 miles (40,075.16 km). It is slightly smaller between the North and South poles at 24,859.82 miles (40,008 km).n addition, Earth is the densest of the terrestrial planets as it is made up of a crust, mantle and core. The Earth's crust is the thinnest of these layers while the mantle comprises 84% of Earth's volume and extends 1,800 miles (2,900 km) below the surface.

What is the Diameter of Earth? Because of this, the diameter of the Earth at the equator is about 43 kilometers (27 mi) larger than the pole-to-pole diameter. The latest measurements indicate that the Earth has an equatorial diameter of 12,756 km (7926 mi), and a polar diameter of 12713.6 km (7899.86 mi).

How big is the Earth? Well, here are some numbers to make you think again! The circumference of the Earth is about 40,000 kilometers or 24,900 miles. This refers to how big the Earth is around it’s fattest middle part, like if you were to measure the length of a string going around the center of the Earth at the equator.ell, here are some numbers to make you think again!

Voyages of Christopher Columbus Accepting the length of a degree to be 56⅔ miles, from the writings of Alfraganus, he therefore calculated the circumference of the Earth as 25,255 km (13,637 nautical miles; 15,693 miles) at most, and the distance from the Canary Islands to Japan as 3,000 Italian miles (3,700 km [2,000 nautical miles; 2,300 miles]).

- where R is the radius of the circle. In this case the radius is that of the Earth which is about 6380 kilometers. Hence the circumference of the Earth (at the equator) is about 2 x 3.14 x 6380 = 40,000 Kilometers.As there is 1.6 km in a mile, so in miles the circumference is about 25,000. Its about 450 miles to San Francisco and its about 3000 miles to New York City from Santa Barbara, California. Click Here to return to the search form.

Eratosthenes' Calculation of Earth's Circumference The actual polar circumference of Earth is just a bit over 40 thousand km (about 24,860 miles). Eratosthenes was a talented mathematician and geographer as well as an astronomer. He made several other important contributions to science.
