How many M is the Earth?
How many M is the Earth?
Earth’s polar radius is 3,950 miles (6,356 km) — a difference of 13 miles (22 km). 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.
What is Earth’s diameter?
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.
What is the diameter of Earth by mile?
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).
How do you measure the diameter of 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.
How many M is space?
Experts have suggested the actual boundary between Earth and space lies anywhere from a mere 18.5 miles (30km) above the surface to more than a million miles (1.6 million km) away.
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”.
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 thick is the Earth?
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.
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.
What is the diameter of Earth 2022?
What is the diameter of Earth, and how does it compare to that of Venus? Earth’s diameter is 7,928 miles.

Who first measured the Earth?
This illustration shows how Eratosthenes actually calculated the circumference of the Earth. At noon on the summer solstice, Eratosthenes measured the length of the shadow cast by a column of known height at Alexandria. With these two lengths, he could solve for the angle between them (θ).
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.
Who calculate the radius of Earth?
Eratosthenes made his measurement on the summer solstice, and had the additional knowledge that on that day the sun was directly overhead at a location a known distance south of Alexandria, on the Tropic of Cancer. This enabled him to compute the Earth’s radius.

Is the Sun a star M?
The Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It’s about 93 million miles (150 million kilometers) from Earth and it’s our solar system’s only star. Without the Sun’s energy, life as we know it could not exist on our home planet.
Is the Earth 25000 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.
How much is the Earth worth M?
According to the calculations of Greg Laughlin, an assistant astronomy and astrophysics professor from the University of California, Santa Cruz, the Earth is worth roughly $5 quadrillion (or $5,000,000,000,000,000).
