What is Earth diameter and circumference?

What is Earth diameter and circumference?

Earth’s circumference (the distance all the way around the equator) is 24,901 miles (40,075 kilometers). Its diameter (the distance from one side to the other through Earth’s center) is 7,926 miles (about 12,756 kilometers).

How long would it take to drive around Earth’s equator?

17 days
In other words, if you could drive your car around the equator of the Earth (yes, even over the oceans), you’d put on an extra 40,075 km on the odometer. It would take you almost 17 days driving at 100 km/hour, 24 hours a day to complete that journey. If you like, you can calculate the Earth’s circumference yourself.

What is the full circumference of the earth?

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 so interesting about the Earth’s circumference?

Circumference. However, the Earth is not quite a perfect circle, and if you measure through the poles, the circumference is a bit shorter—24,859.82 miles. The Earth is a bit wider than it is tall, giving it a slight bulge at the equator; this shape is known as an ellipsoid, or, more properly, a geoid.

What does the Earth weigh?

5.972 × 10^24 kg
Earth/Mass

How fast would you have to go to reach Alpha Centauri in 100 years?

approximately 13,411 km/s
The journey to Alpha Centauri B orbit would take about 100 years, at an average velocity of approximately 13,411 km/s (about 4.5% the speed of light) and another 4.39 years would be necessary for the data to begin to reach Earth.

How was Earth named?

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’.

What is the circumfrence of the Earth in meters?

What is the circumference of the eath?

The circumference of the Earth in kilometers is 40,075 km, and the circumference of the Earth in miles is 24,901.

How is the circumference of the Earth determined?

Eratosthenes ‘ method for determining the circumference of the Earth, with sunbeams shown as two rays hitting the ground at two locations in Egypt – Syene (Aswan) and Alexandria. Earth’s circumference is the distance around the Earth, either around the equator (40,075.017 km [ 24,901.461 mi ]) or around the poles (40,007.863 km [ 24,859.734 mi ]).

How many nautical miles is the circumference of the Earth?

One minute of arc is 1/21,600th of a full circumference, and so the polar circumference of the earth… is 21,600 nautical miles.” In 1617 the Dutch scientist Willebrord Snellius assessed the circumference of the Earth at 24,630 Roman miles (24,024 statute miles).

How do we measure the circumference of Earth?

Use a protractor to measure the angle between the string and the meterstick in degrees. Write this angle down. Look up the distance between your city and the equator. Calculate the circumference of the Earth using this equation: Circumference = 360 x distance between your city and the equator / angle of shadow that you measured

What is the average circumference on Earth?

The Earth’s circumference – the distance around the equator – is 40,075 kilometers around. That’s sounded nice and simple, but the question is actually more complicated than that. The circumference changes depending on where you measure it. The Earth’s meridional circumference is 40,008 km, and its average circumference is 40,041 km.

Who estimated the circumference of Earth?

” Eratosthenes Teaching in Alexandria” by Bernardo Strozzi . The circumference of the Earth is 40,075 km, and the Greek geographer Erastosthenes was the first person to estimate the Earth’s circumference nearly accurately.

How is the Earth’s circumference calculated?

Circumference of earth can be calculated using the diameter of earth which is 12742 km. Convert diameter of earth to radius by dividing it by r = d/2 = 12742/2 r = 6371 km
