# Whats the diameter of earth

The Earth has a diameter of 7926.3 miles at the equator, and its circumference. The distance around the earth at the equator, is 24901.55 miles.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. 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. Radius, diameter and circumference  The radius of Earth at the equator is 3,963 miles (6,378 kilometers), according to NASA’s Goddard. 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.

## Earth diameter

Diameter of the Earth. In this project you will use the method that Eratosthenes used to measure the Earth. You will need to accurately measure the length. Then, knowing the distance to Aswan, it’d be simple to calculate Earth’s radius. (You geometry students, try that one.) There was no accurate timekeeping back. 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. The Earth has a diameter of 7926.3 miles at the equator, and its circumference. The distance around the earth at the equator, is 24901.55 miles.Earth’s circumference is the distance around Earth. Measured around the Equator, it is 40,075.017 km (24,901.461 mi). Measured around the poles,

## Diameter of earth in miles

Because the earth is spheroidal, it is not exactly meaningful to speak of its width. You can speak of its diameter, which you can measure through the. 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. The Earth has a diameter of 7926.3 miles at the equator, and its circumference. The distance around the earth at the equator, is 24901.55 miles.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. 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.

## 65000 km from earth

11-30 miles, Stratosphere of Earth’s atmosphere, including the ozone layer. 65,000 feet, Hot air balloon altitude record. 63,360 feet, Twelve miles high.Planets having active magnetospheres, like the Earth, are capable of mitigating or blocking the effects of solar radiation or cosmic radiation, The magnetic field of our planet — otherwise known as the magnetosphere — extends out to about 65,000 kilometers (40,000 mi) above the. On 25 July 2019, the asteroid, which is the size of a football field, flew between the Earth and the Moon, coming within 65,000 km of our. A laser fired from Earth to the Moon is 1,000 m wide when it hits the Moon at 384,000 km away. So a laser 65,000 km away would be about 1/6th of that,

## Density of Earth

The average density of the Earth is 5.513 g/cm about the same as Mercury and Venus and 40% greater than Mars. Earth’s density can be calculated from it’s Mass. Early plumb-line and torsion balance Earth density estimates have been compiled by Hughes (2006) who noted that from early to mid 19th century times, torsion. The current best estimate for the mass of Earth is M = 5.9722×1024 kg, with a standard uncertainty of 6×1020 kg (relative uncertainty 10?4). The recommended. The gravitational constant g is given as: g=R2GM orM=Gg×R2 ?Density D=volumemass =G×Ve g×R2 (Where Ve is the volume of the earth )The density of the inner ‘solid’ core is between 9.9-12.2 g/cm3 and the outer core’s density is between 12.6-13 g/cm3. It is through our study of the Earth that.
