What is the real diameter of the Earth in miles?

What is the real diameter of the Earth in miles?

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.

Is Earth 8000 miles wide?

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).

Is the Earth 24000 miles?

Today, most scientists set the earth’s circumference at 40,096 kilometers (24,901 miles). This gives Eratosthenes’ estimate less than a one percent error—an excellent approximation of the earth’s circumference. Syene is not on the Tropic of Cancer, where the sun’s rays are directly overhead during the summer solstice.

How thick is the Earth miles?

Earth’s crust varies in thickness from 35 to 70 kilometers (22 to 44 miles) in the continents and 5 to 10 kilometers (3 to 6 miles) in the ocean basins.

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 many km round is the Earth?

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.

How heavy is Earth?

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. In northwestern Canada, they discovered rocks about 4.03 billion years old.

What is Earth’s longest distance?

The longest continuous north–south distance on land is 7,590 km (4,720 mi) along the meridian 99°1’30″E, from the northern tip of Siberia in the Russian Federation ( 76°13′6″N 99°1′30″E), through Mongolia, China, and Myanmar, to a point on the south coast of Thailand ( 7°53′24″N 99°1′30″E).

How fast does Earth spin?

With this information, to work out how fast Earth is spinning we need only our planet’s circumference. At the equator, its circumference is roughly 40,075 kilometres, so dividing this by the length of day means that, at the equator, Earth spins at about 1670 kilometres per hour.

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 com​posed of basalt.

Is space 50 miles above Earth?

For NASA and the U.S. military, for example, space starts at an altitude of 50 miles (around 80 kilometers), according to NOAA. However to the international community, including the Fédération Aéronautique Internationale (opens in new tab) (FAI), space starts a little higher, at 62 miles (100 km), at the Kármán line.

What is the real name of Earth?

It is a common misconception that “Terra” is the internationally-recognized scientific name of the planet, but in reality Earth does not have an official international name. The standard English name of the planet, including in science, is “Earth”.

How deep is Earth’s core?

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 core hotter than sun?

That led to the conclusion that the temperature of the center of the Earth is about 6000 degrees Celsius – a temperature about 9% higher than what exists on the surface of the Sun.

How big is space in miles?

A common definition of space is known as the Kármán Line, an imaginary boundary 100 kilometers (62 miles) above mean sea level.

What planet has a diameter of 87000 miles?

Jupiter is the largest planet in the solar system. It is approximately 87,000 mi (140,000 km) in diameter, while Earth is only 8,000 miles (12,800 km) across. The giant storm on Jupiter, commonly known as the Great Red Spot, could easily fit the entire Earth inside of it.

What is the real 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.

What is the real weight of Earth?

(Inside Science) — The Earth isn’t even close to being the largest planet in our solar system, but it’s also no lightweight, weighing in at a whopping 13 thousand, 170 billion trillion pounds, or 13,170,000,000,000,000,000,000,000. To put that into context, a male African bush elephant tips the scale at 13,000 pounds.
