What is the current diameter of Earth?
What is the current diameter of Earth?
The diameter of a circle is twice the radius, giving us a diameter for Earth of 12,756 km. Note: The Earth is almost, but not quite, a perfect sphere. Its equatorial radius is 6378 km, but its polar radius is 6357 km – in other words, the Earth is slightly flattened.
What is Earth diameter and circumference?
The distance between the north and south poles is approximately 7900 miles while the equatorial diameter is slightly larger at 7930 miles. The circumference of the Earth is just its average diameter, 7915 miles, times the number pi, where pi is 3.14159. This gives us about 25,000 miles for the Earth’s circumference.
What are the two diameters of Earth?
From the available mathematical data the equatorial diameter of the earth is about 12756 km and also the polar diameter of the earth is about 12713.6 km.
What is the largest diameter of the Earth?
Earth’s diameter at the Equator is about 12,756 kilometers (7,926 miles). At the poles, the diameter is about 12,714 kilometers (7,900 miles). Earth’s equatorial bulge is about 43 kilometers (27 miles).
Who named Earth?
All of the planets, except for Earth, were named after Greek and Roman gods and godesses. The name Earth is an English/German name which simply means the ground. It comes from the Old English words ‘eor(th)e’ and ‘ertha’. In German it is ‘erde’.
How heavy is Earth?
What is Earth made of?
The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite. There are two types of crust; oceanic and continental. Oceanic crust is denser and thinner and mainly composed of basalt.
How thick is planet Earth?
It’s also highly variable in its thickness. Under the oceans (and Hawaiian Islands), it may be as little as 5 kilometers (3.1 miles) thick. Beneath the continents, the crust may be 30 to 70 kilometers (18.6 to 43.5 miles) thick.
How old is Earth?
Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date.
What is half Earth called?
Any circle drawn around the Earth divides it into two equal halves called hemispheres. There are generally considered to be four hemispheres: Northern, Southern, Eastern, and Western. The Equator, or line of 0 degrees latitude, divides the Earth into the Northern and Southern hemispheres.
What is the 2 layer of the Earth called?
Mantle: It is the second layer of the Earth. It is about 2,900 km deep and has two parts: – the upper mantle, which contains solid and molten rocks. – the lower mantle, which mainly contains solid materials.
What is Earth 2.0 called?
Kepler-452b (sometimes quoted to be an Earth 2.0 or Earth’s Cousin based on its characteristics; also known by its Kepler Object of Interest designation KOI-7016.01) is a super-Earth exoplanet orbiting within the inner edge of the habitable zone of the sun-like star Kepler-452 and is the only planet in the system …
Where is center of Earth?
Earth’s core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth’s surface, and has a radius of about 3,485 kilometers (2,165 miles).
Is Earth bigger than a black hole?
The gigantic black hole, not counting the giant rings of trapped light orbiting it, is about 23.6 billion miles (38 billion kilometers) across, according to Science News. Meanwhile, the Earth is just 7,917 miles in diameter — meaning our planet wouldn’t even be a drop in the bucket of the giant, black void.
What is the largest circle called?
A great circle is the largest possible circle that can be drawn around a sphere. All spheres have great circles. If you cut a sphere at one of its great circles, you’d cut it exactly in half. A great circle has the same circumference, or outer boundary, and the same center point as its sphere.

What is the diameter of the Earth 2022?
What is the diameter of Earth, and how does it compare to that of Venus? Earth’s diameter is 7,928 miles.
What is the electric current of Earth?
The total current flowing in the global circuit, and therefore the total reaching the surface, is about 1,800 amperes. The potential of the upper atmosphere is about 300 kilovolts compared with the surface.
What is the current orbit of the Earth?
Earth orbits the Sun at an average distance of 149.60 million km (92.96 million mi) in a counterclockwise direction as viewed from above the Northern Hemisphere. One complete orbit takes 365.256 days (1 sidereal year), during which time Earth has traveled 940 million km (584 million mi).
What is the current shape of the Earth?
The Earth is an irregularly shaped ellipsoid. While the Earth appears to be round when viewed from the vantage point of space, it is actually closer to an ellipsoid.
