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).
What is the size diameter of Earth in miles and kilometers?
How many miles is the diameter of the earth?
about 24,901 miles Using those measurements, the equatorial circumference of Earth is about 24,901 miles (40,075 km). However, from pole to pole — the meridional circumference — Earth is only 24,860 miles (40,008 km) around. Our planet's shape, caused by the flattening at the poles, is called an oblate spheroid.
How big is the earth in KM?
6,371 kmEarth / Radius
What is the diameter in KM?
Mean Diameter: This is what is known as its “mean diameter”, which in Earth's case is the sum of its polar and equatorial diameters, which is then divided in half. From this, we get a mean diameter of 12,742 km (7917.5 mi).
What is Earth’s size?
6,371 kmEarth / Radius
How is the diameter of the Earth measured?
Both of these values are very close to the accepted modern values for the Earth's circumference and radius, 40,070 km and 6378 km respectively, which have since been measured by orbiting spacecraft. The diameter of a circle is twice the radius, giving us a diameter for Earth of 12,756 km.
How big is Earth vs universe?
The Diameter of the earth is 12,742 km. One parsec is about 30 Trillion km -thats 30,000,000,000,000 km. The observable universe is about 28 Billion parsecs across.
How deep is the Earth in miles?
The distance to the center of the Earth is 6,371 kilometers (3,958 mi), the crust is 35 kilometers (21 mi) thick, the mantle is 2855km (1774 mi) thick — and get this: the deepest we have ever drilled is the Kola Superdeep Borehole, which is just 12km deep.
What is the diameter of the Earth NASA?
about 8,000 miles Earth is the fifth-largest planet in the solar system. Its diameter is about 8,000 miles.
