If we accept the account of Strabo that Eratosthenes measured the circumference of the earth as 252,000 stadia, the circumference would be 24,662 miles, and the polar diameter 7,850 miles-only 50 miles short of the true polar diameter. This is considered to be one of the first great ...
The equatorial diameter of the earth is 8,000 (7,926) miles and the circumference around the earth is 25,000 (24,830) miles. The earth is surrounded by atmospheric air up to about 100 miles deep, but most of the mass of air is within 10 miles from the earth’s surface. The...
What are the effects of distance and mass on the gravitational pull of the planets? How fast does the International Space Station travel? How fast are asteroids moving in space? What is the circumference and diameter of Earth? A satellite is circling Earth with a speed of 7.8 km/s. The ...
If you could measure the distance of the earth starting at the North Pole and ending at the South Pole, you would need a tape measure that is 7,899.83 miles long. If you measured the diameter of the earth by poking a probe in at one side of the equator and exiting on the exact opp...
What is the radius of Earth in meters? Facts about the earth Since the earth is a sphere, we can measure its diameter and radius. The diameter is the distance from side to side, if you could put a ruler right through the center of the planet. ...
In terms of size relative to its parent planet, the Moon is unusually large. Its diameter is 3476 kilometers (2160 miles), which means it is around 27 percent the size of Earth. The next biggest moon in the solar system by this measure, Triton, is only about 5 percent the size of ...
The Earth is about 7,926 miles (12,756 km) in diameter. The Earth is the fifth-largest planet in our Solar System (afterJupiter,Saturn,Uranus, andNeptune). Eratosthenes(276-194 BC) was a Greek scholar who was the first person to determine the circumference of the Earth. He compared the...
Earth is the fifth-largest planet in thesolar system, behind Jupiter, Saturn, Uranus and Neptune. With a diameter of86,881 miles(139,822 km),Jupiter— the largest planet in the solar system — is 11 times wider than Earth. The gas gianthas a volume of 343 trillion cubic miles(1,431 ...
While it's a satellite ofEarth, the moon, with a diameter of about 2,159 miles (3,475 kilometers), is bigger thanPluto. (And there are four other moons in oursolar systemeven bigger than ours.) You may like How to photograph the moon using a camera: techniques, kit, and settings ...
Earth is classified as the largest of the terrestrial planets based on its circumference and diameter as well. At the equator, Earth's circumference is 24,901.55 miles (40,075.16 km). It is slightly smaller between the North and South poles at 24,859.82 miles (40,008 km). Earth's diamet...
