Describe the Size of the Earth

Our result is that the observable universe is 10²⁰ 100000000000000000000 times larger than Earth. How big is Earth.

How Big Is The Earth Size Comparison Actual Size Facts

Contour maps show the shape of the.

. Planet Earth has an abundance of water that makes it unique and perfect for life to exist. Early astronomers knew that Earth was round for several reasons. Although they knew it was a sphere they didnt know how big the sphere was.

What is the size and shape of earth. 6 rows Below is a table with many of the pieces of the data used to measure the size of the Earth. The radius of Earth at the equator is 3963 miles 6378 kilometers according to NASAs Goddard Space Flight.

The atmosphere and hydrosphere are so thin compared to the entire size of the Earth that if drawn as seen from space the ink would be thicker than each of the two layers would be if drawn to scale. Mercury is the smallest terrestrial planet and overall the smallest planet in our Solar System. Earths mean sea level surface.

It has a diameter of only 4879 km. The average diameter of the earth is 12742 km. Its diameter the distance from one side to the other through Earths center is 7926 miles about 12756 kilometers.

Earth and Solar System Size Comparison. Of that 292 is covered by land and 708 is covered by water. Joshua Kennon 9 years ago.

Just for comparison thats 35 times as much surface area as Mars. If the Sun were as tall as a typical front door Earth would be the size of a nickel. Fitting ellipsoids and coordinate systems.

So if you scaled the observable universe down to the size of Earth youd be scaling everything in the Universe including Earth itself down by this same factor. Small groups of students could become experts on different zones and act as tour guides on a tour which could be constructed to scale along a corridor eg. Earth makes a complete orbit around the sun a year in Earth time in.

The Earth has a diameter of 79263 miles at the equator and its circumference or the distance around the earth at the equator is 2490155 miles. The diagram on this page is an exaggeration - in reality the difference is very small. We round this up to 13000km.

Radius diameter and circumference. Really it is a oblate sphere on earth and its size is diameter of earth 7926 12756kmin diameter. The Earth as being a disk with a circumference of about 78225 miles and a diameter of 24900 miles.

The actual circumference of the Earth is 40 075 40075 4 0 0 7 5 km at the equator. When Earth was a young planet a large chunk of rock smashed into it displacing a portion of Earths interior. Earth is the third planet from the Sun at a distance of about 93 million miles 150 million km.

Describe the Geoid shape. Planet Earth has an abundance of water that makes it unique and perfect for life to exist. Its not known exactly how Plato or Archimedes arrived at their calculations but Platos.

As of a few years ago 2009 I believe the estimate of the habitable planets in the observable universe published by Alan Boss astrophysicist at Carnegie Institution in Washington DC was ten thousand billion billion. Highest and lowest points. It is not certain which definition of stade Eratosthenes used.

3 As the World Turns A day on Earth is 24 hours. As a result in order to calculate the exact surface area mathematicians have developed a specific formula which has detemined that the Earths surface area is approximately 196939900 square miles 5101 million km² and of that 57505693767 square miles 1489 million km² is the land area not covered by oceans. He calculated Earths circumference at 26000 miles 42000 km only five percent away from the modern accepted value of 24901 miles 40074 km.

2 Third Rock Earth orbits our Sun a star. For land the geoid would be the height to which water would rise in a. Its probably about 025 miles long.

The sun and moon are both disks about 32 miles in diameterand are about 3000 miles. The equator is 24901 miles. Some 150 years later the mathematician Archimedes estimated it to be 48309 kilometers 30000 miles.

The diameter of the Earth at the poles is 78998 miles. He also may have been lucky. The resulting chunks clumped together and formed our Moon.

That means if you stretched out this track it would fit around the Earth 99604 times. Earth is slightly smaller when measured between the North and South Poles which gives a diameter of 7907 miles 12725 kilometers. If 1mm 1km the journey is 64 metres long.

The Earth is 12756km at the equator and 12714km from pole to pole. Regardless he calculated the size of the earth to within an order of magnitude and possibly got very close. Density mass and volume.

- earth is flattened at the poles and extended at the equator. Planet Earth has an abundance of water that makes it unique and perfect for life to exist. - depressions and bulges.

That is 10000000000000000000000 Earth-like planets. The surface area of Earth is 510072000 square kilometers. Earths circumference the distance all the way around the equator is 24901 miles 40075 kilometers.

Students can then describe their own imaginary journey into the Earths interior using their knowledge of correct science. With a radius of 1080 miles 1738 kilometers the Moon is the fifth largest moon in our solar system after Ganymede Titan Callisto and Io. Variation in Eratosthenes estimates based on stade length.

It is thought this shape was caused by the rotation of the early molten Earth. The Earth is widest at the equator. So the size of the scaled-down Earth would be.

More specifically the diameter of the planet at the equator is 12756 km and the longitudinal diameter at the poles is 12713 km. The philosopher Plato 400 BCE declared the earths circumference to be 64412 kilometers 40000 miles.
