Eratosthenes of Cyrene (276 BC - 194 BC) was a Greek mathematician, poet, athlete, geographer and astronomer. He made several remarkable discoveries and inventions: he devised a system of latitude and longitude. He was the first person to calculate the circumference of the Earth with remarkable accuracy, and the tilt of the earth's axis.

What is the approximate compression of the earth?
The Earth's compression is estimated to be around 0.5-1%. This means that the Earth's diameter at the equator is smaller than its diameter at the poles due to the planet's rotation and gravitational forces.
Is the diameter of earth 25000 miles?
That is a very good estimate of the earth's circumference in miles, 24,901.5 miles. It is not earth's diameter. 7926 miles is an estimate of earth's diameter.
What is the difference in size between Mercury and the Earth?
Mercury is significantly smaller than Earth, with a diameter of about 4,880 kilometers compared to Earth's diameter of about 12,742 kilometers. This makes Mercury roughly one-third the size of Earth in terms of diameter.
What day of the week was the first day of the Earth?
If you are a Christian, then the first day of the earth was Monday
What is the width of earth?
Not including any mountains, the greatest width of the Earth is its equatorial diameter, which is about 12756 kilometers or about 7926 miles.
What is the approximate compression of the earth?
The Earth's compression is estimated to be around 0.5-1%. This means that the Earth's diameter at the equator is smaller than its diameter at the poles due to the planet's rotation and gravitational forces.
Does Eratosthenes determine Earth's diameter?
Yes, Eratosthenes estimated the Earth's diameter using the angle of the sun's rays at two different locations on the same day. By measuring the difference in the angles, he was able to calculate the Earth's circumference and thus its diameter.
Who first estimated the circumference of the Earth?
erathosthenes was the first ,
Who was the first to discover the earth's diameter?
Eratosthenes
How many times would earth fit inside titan?
Titan, Saturn's largest moon, is estimated to have a diameter about 50% larger than Earth's moon. Given that Earth's diameter is about 12,742 kilometers and Titan's is about 5,151 kilometers, you could fit roughly 2.5 Earths along the diameter of Titan.
What is the combined diameter of Earth and Earth's moon?
The combined diameter of Earth and earth's moon is 16,232 milometers, or 11% the diameter of Jupiter, 14% the diameter of Saturn, 32% the diameter of Uranus, and 33% the diameter of Neptune.
What is the diameter of thr earth?
The diameter of the earth is around 12,756.2 km
Is mercury larger or smaller than earth diameter?
Mercury's diameter is 0.3825 times that of Earth's
What is earths moons diameter?
2½ Moon Diameter = Earth's Diameter- 1 Moon Diameter. Earth's Diameter = 7/2 Moon
Is the diameter of earth 25000 miles?
That is a very good estimate of the earth's circumference in miles, 24,901.5 miles. It is not earth's diameter. 7926 miles is an estimate of earth's diameter.
Compared to Earth's diameter the sun's diameter is about?
the sun's diameter is about 110 times greater than the diameter of our earth.
How does the Earth's diameter compare to the Sun's diameter?
The Sun's diameter is about 108 times the size of Earth's. (The Sun has a diameter of about 865,000 miles compared to Earth at 8000 miles.)
