What is polar diameter?

The diameter of a planet measured from pole to pole.

### What is the diameter of the South Pole?

At roughly 2,500 km (1,600 mi) in diameter and between 6.2 and 8.2 km (3.9–5.1 mi) deep, it is one of the largest known impact craters in the Solar System. It is the largest, oldest, and deepest basin recognized on the Moon.

What is the length of world?

However, from pole to pole — the meridional circumference — Earth is only 24,860 miles (40,008 km) around. Our planet’s shape, caused by the flattening at the poles, is called an oblate spheroid. Those numbers make Earth just slightly bigger than Venus, whose equatorial radius is about 3,761 miles (6,052 km).

#### What is the difference between the length of its polar and equatorial diameter?

The planet’s rotation causes it to bulge at the equator. 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).

#### What is the difference between the equatorial diameter and the polar diameter?

Geodesy is the science that studies the shape and size of the Earth. This means the earth’s equatorial diameter is 7,926 miles, while its polar diameter is 7,900 miles. Although the difference between equatorial and polar diameters is only 26 miles, the oblate shape of the earth complicates geographical matters.

What is the distance between North Pole and South Pole?

How far is it from North-Pole to the South Pole? From North-Pole to the South Pole, it is 12,436.12 mi (20,014.00 km) in the north.

## How big is the Earth compared to a human?

The Earth is about 3.5 million times larger than a human.

## How was the diameter of the Earth calculated?

This means that Eratosthenes estimated the circumference of the Earth to be about 40,000 km. He also knew that the circumference of a circle was equal to 2 times π (3.1415…) times the radius of the circle. The diameter of a circle is twice the radius, giving us a diameter for Earth of 12,756 km.

What is the length of Earth’s polar 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).
