What is the average radius of the Earth at the equator?
3,958.8 miEarth / Radius
How much is the equatorial diameter?
12,756 km
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 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).
What is the average distance from the equator?
68.703 miles
Each degree of latitude is approximately 69 miles (111 kilometers) apart. At the equator, the distance is 68.703 miles (110.567 kilometers). At the Tropic of Cancer and Tropic of Capricorn (23.5 degrees north and south), the distance is 68.94 miles (110.948 kilometers).
What is the centripetal acceleration on the Earth’s surface at the equator?
about 0.03 m/s2
Earth’s period of rotation is a sidereal day (86164.1 seconds, slightly less than 24 hours), and the equatorial radius of the Earth is about 6378 km. This means that the centripetal acceleration at the Equator is about 0.03 m/s2 (metres per second squared).
What is Earth’s radius?
What is the radius of the orbit of the Earth?
The radius of the earth’s orbit around the sun (assumed to be circular) is 1.50×108 1.50 × 10 8 km, and the earth travels around this orbit in 365 days.
What is Earth radius?
How far is the center of the Earth?
6,371 kilometers
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.
How far is Earth from center of universe?
25,800 light-years
The calculations indicate the Earth is really 25,800 light-years from galactic center and traveling at 141 miles per second (227 km/s).
What is the distance to the center of the Earth?
6,371km
Congratulations! The distance to the centre of the Earth has been taken as the volumetric mean radius of the Earth: 6,371km. Note that this distance and the depth of geological layers varies across geographical locations.
What is the gravity at the equator?
Using Newton’s law of gravity, we find that the force of earth’s gravity on your body at the equator is 9.798 m/s2 times the mass of your body, whereas at the poles it is 9.863 m/s2 times the mass of your body. The earth’s centrifugal force also varies with latitude.
Is gravity less at the equator?
Gravity is often assumed to be the same everywhere on Earth, but it varies because the planet is not perfectly spherical or uniformly dense. In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet’s rotation.
