How long is the Earth’s diameter in KM?

How long is the Earth’s diameter in KM?

The diameter of the Earth at the equator is 12,756 kilometers (km).

Is the Earth 40000 km?

In 200 B.C. Eratosthenes estimated Earth’s circumference at about 46,250 kilometers (28,735 miles). Today we know our planet’s circumference is roughly 40,000 kilometers (24,850 miles).

Is the diameter of the Earth 4000 km?

Its diameter (the distance from one side to the other through Earth’s center) is 7,926 miles (about 12,756 kilometers).

What is Earth’s diameter?

How thick is 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.

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.

At what speed is Earth?

As schoolchildren, we learn that the earth is moving about our sun in a very nearly circular orbit. It covers this route at a speed of nearly 30 kilometers per second, or 67,000 miles per hour.

How many kms is deep Earth?

The average distance to the centre of the Earth is 6,371 km or 3,959 miles. In other words, if you could dig a hole 6,371 km, you’d reach the center of the Earth. At this point you’d be in the Earth’s liquid metal core.

What is Earth made of?

Earth is composed of four main layers, starting with an inner core at the planet’s center, enveloped by the outer core, mantle, and crust. The inner core is a solid sphere made of iron and nickel metals about 759 miles (1,221 kilometers) in radius.

What layer of the Earth is 5000 km?

Inner core (5000 km – 6370 km below the Earth’s surface). 2 % of the Earth’s total mass.

Which planet has the most rings?

Glorious Rings Saturn has the most spectacular ring system, with seven rings and several gaps and divisions between them.

What is the volume of Earth?

Density, mass and volume Earth’s mass is 6.6 sextillion tons (5.9722 x 1024 kilograms). Its volume is about 260 billion cubic miles (1 trillion cubic kilometers).

How many Earths are in the sun?

Size and Distance Many stars are much larger – but the Sun is far more massive than our home planet: it would take more than 330,000 Earths to match the mass of the Sun, and it would take 1.3 million Earths to fill the Sun’s volume. The Sun is about 93 million miles (150 million kilometers) from Earth.

Why is it called diameter?

In geometry, a diameter (Greek words dia = through and metro = measure) of a circle is any straight line segment that passes through the center of the circle and whose endpoints are on the circle.

What is inside Earth?

Earth’s Interior. The Earth is divided into three main layers. The dense, hot inner core (yellow), the molten outer core (orange), the mantle (red), and the thin crust (brown), which supports all life in the known universe. Earth’s core is the very hot, very dense center of our planet.

Which layer is liquid?

The outer core is the third layer of the Earth. It is the only liquid layer, and is mainly made up of the metals iron and nickel, as well as small amounts of other substances. The outer core is responsible for Earth’s magnetic field. As Earth spins on its axis, the iron inside the liquid outer core moves around.

What is the hottest layer of the Earth?

The inner core is the hottest layer, above 9000 Fahrenheit and it is 1250 km thick! Crust: The Earth’s thinnest layer!

What planet has a diameter of 12000 km?

— Venus, with a diameter of about 7,500 miles (12,000 km), is slightly smaller than Earth. It is the second planet from the Sun and is Earth’s closest planetary neighbor.

What is the largest diameter in KM?

Jupiter is the most massive planet in the solar system. It has an equatorial diameter of about 143,000 km (88,900 miles).

How long is the universe in KM?

Explanation: The diameter of the Observable Universe is about 46.5 billion light years or 4.40 x 1023 km.

What is Earth’s orbital radius in km?

3 The radius of the earth and the radius of orbit around the sun are 6371 km and 149×109 km respectively.
